Funk's 23MT OEM+ Build

[Funkjaw]

Curious as to why you went with Conti DWS06 instead of the EC02, as the latter seems to grip better

Primarily because I live in TX where we have backroads with a constant layer of dust/debris and weather patterns that look like this:

I've ran EC02s in California when I lived there, but not yet in Texas - so it's not that I am opposed to the idea, I just feel DWS06 might be better under these conditions. With that said I'll ask around locally and see how people feel about EC02s year round here.

I just ordered forged rims from Alibaba as well. OEM replicas that are 19x11 +35 for the rear with 6061-T6 aluminum. I heard good things and I like the car looking stock

Would love to hear your feedback on the rims and the vendor you worked with

Ah ok, I saw you're in Austin. I lived in SA but it was over 20 yrs ago, and would have though summer tires would be fine, but not sure if weather has changed since then.

2023 Manual 3.0 Premium - Red
Purchased at 8000 miles from a Toyota dealership. Car was leased for one year by the previous owner then after the lease was up the dealership put it for sale.

Background
When I bought the car my wife insisted I wouldn't be able to keep it nice because I turn every car into a shitbox at some point. And while she may have been correct with the other ~25 or so RWD sports cars I have owned - I'll be damned if I don't prove her wrong this one time!

So this build is all about being OEM+ with the following criteria:

• Car will remain nice, comfortable, and quiet.
• Modifications will only serve to rectify a problem I personally have with the car.
  • No modifications will be done just for the sake of doing a modification
• Modifications have to add more value than they subtract for me to consider it
  • Example: if a modification adds stability but makes the car unbearably noisy, I don't see it as a worthwhile modification.
• Modifications can not void OEM powertrain warranty (for now)
  • No tune, larger turbo, catless DP, etc. As long as I am still making payments on it, I want the powertrain warranty intact.

How the car will be driven:

• 1st and foremost it's my daily driver
• 95% street and canyon roads (on the weekends)
• Driven in all weather conditions - canyon roads + rain is my idea of a good time.
• I tend to drive it like I stole it
  • If there's an empty parking lot I will be doing donuts
  • If there is a long straight I will be slapping gears
• It may see a track day here or there, but not very often as I have dedicated track cars for this purpose

I have two major complaints about the car that I will be addressing with modifications right off the bat

• The rear end is unstable from factory when being driven near the limits, and frankly it can't even handle OEM power levels
• The intake and exhaust is too damn quiet even in sport mode

I will be tracking all modifications and maintenance on google sheets, which is embedded below and (hopefully) updates real time. Scroll to the right to see more columns containing information such as cost and status.

Feel free to reach out if you have any thoughts or questions! Thanks for viewing.

Parts Discussion

Here I'll be briefly talking about parts as I get them installed, or if I remove them, why I did.

Dashcam by Fitcamx
https://www.amazon.com/dp/B0CMTX8NJ9

I really like this because it seamlessly replaces the existing rear view mirror enclosure for an OEM look. The video and audio quality are good enough for a police report for sure, but don't expect to use it as a race cam.​

​

Reinforced Jack Pads by Verus Engineering
https://www.verus-engineering.com/s...k-puck-toyota-supra-3813?category=67#attr=638

​

When I bought the car I reached out to a friend who had a MKV and asked him what were some frustrations he had, and he listed the OEM jack pads breaking easily as his #1. These were a no brainer after hearing that. They were easy to install and look great.​

PPF by Refined PPF here in Austin
https://www.refinedppf.com/

​

This is something I would never have considered for a car because I am of the type that believes battle scars are cool. But I knew getting this would make my wife happy as she also drives the car, so I am glad I did. I had them do all the high risk areas for about 70% coverage. It was 3300 bucks, ouch!​

​

Rock Guards by ZL1 Addons
https://zl1addons.com/products/supra-standard-rock-guards?variant=42264127373483

Another must have that goes along the lines of keeping the body clean. They were also pretty cheap and easy to install - win/win​

Differential lockdown/brace by Twisted Tuning
https://twistedtuning.com/products/...ial-lockdown-brace-kit?variant=40961308164144

I got these as I believed this would solve all my problems with wheel hop. Sadly it did not. It did reduce some wheel hop and provide better rear stability however. And because it didn't add to NVH I decided to keep it on.​

​

Anti-Buffeting Wind Deflectors by Verus Engineering
https://www.verus-engineering.com/s...tors-mk5-toyota-supra-1471?page=2&category=57

First time I tried to drive with the windows down I nearly blew my ear drums out. Some quick googling said these would be the fix. I will say these 100% fixed the problem no doubt and very happy I put them on. BUT you can likely get WAAAAY cheaper deflectors that provide the same benefit. I'm just a little bougie at times.​

​

CDV Delete by Free.99

This is a well known mod to do to manual BMW cars and the benefits are seen just as much on the A90 as they are on other BMW platforms. If you have a manual this should be one of if not the first mod you do. Saves the the life of the clutch, makes clutch kicks actually work, and makes shifting gears smoother.​

​

Engine Mount Inserts by PowerFlex
https://www.powerflexusa.com/shop/p...ine-mount-insert-4492?category=2442#attr=2567

I really like this mod. It reduced wheel hop and added very minimal NVH to Idle that goes away quickly. It also increased throttle response and no joke seems to have made shifts crisper between gears. I would do this mod 10 times over!​

​

Poly Transmission Mounts by PowerFlex
https://www.powerflex.co.uk/product-details/Transmission+Mounting+Bush+(Fast+Road)/14370.html

I did not like these. They did nothing for wheel hop that I could tell and added a ton of NVH, so much so that I could feel it in the steering wheel. For a track car or a zero fucks given car sure these would be great, but not for an OEM+ build like mine. So I reverted back to stock.​

​

Cold Air Intake by MST
https://www.mst-performance.com/products/ty-sup05

This intake is badass. Not only does it produce super cool boostie boi sounds, but it also surprisingly keeps AITs close to what the OEM airbox does. Plus it adds a couple HP! Downside is it was a pain in the ass to install.​

Current picture of car - Feb 2025​

Dash cam is a very interesting design.

I would love to have an integrated radar detector in the same kind of housing. Or at least something to help it blend.

how does it perform at night?

How did the drive characteristics under wot change with the eibach rear sway bar?

Instead of the car wanting to squirm around, it just squats into the road and grips. Another unexpected benefit is that the nose lift and dive is also substantially reduced.

I know that stiffer sway bars are only supposed to affect lateral roll and have no impact on comfort if you hit a bump with both wheels at the same time (e.g. speed bumps). However, neither of these have been true in my experience with the Eibachs. The car is substantially firmer in every direction.

If you are already running lowered springs and added the Eibachs, it may become a little too much if you are after a comfortable daily. Perhaps a slightly softer brand would be the right choice if you have some less than perfect roads about. Also, as you sit far back and close to the rear axle in this car the impact in cabin is definitely amplified.

If you are lower and find you need to drive up driveways at an angle regularly be careful as the Eibachs being so stiff can result in rear wheel lift, even on the softest setting. As the Supra has clutch based diff, if one wheel lifts then power to both is cut and you're left hanging unless you had enough speed to get past the hang and have both wheels on the ground again.

Additionally, adding sway bars will bring out a few new in cabin rattles that weren't there before so if that bugs you have some felt tape handy. I've removed and padded all the panels around the seatbelt dispensers and rear brace and all the additional rattles are gone.

That's probably a bit more info than you were wanting but these are all things I hadn't realised or considered before installing. None of them are show stoppers for me, but they might be for others.

No that’s perfect, thanks for the detailed reply.

I’ll see if the lane wandering is eliminated with the current parts list in the spring, if not I’ll have to give these a shot as well.

I think it performs excellent at night, but you can see for yourself. Here is raw 4k footage from three different light conditions while driving: overcast, dusk, night. Make sure you adjust the quality setting to 4k.

Thanks for the reply this is great. Sounds like an aftermarket rear sway bar will reduce how unsettled the car gets when going off throttle to straighten out a drift - among things.

Installed a cheap eBay duckbill spoiler. Looks great, although color doesn't 100% match which doesn't surprise me for being a cheap pre-painted part. Will hold me over until I decide to put a big wang on it.

Got the Verkline rear traction links and toe links installed and the car aligned.

Here is the before - as you can see even matching the lengths of the OEM links the car was still waaaay outta spec. I had to drive it 40 minutes to Firestone with a steering wheel that was ~35 degrees off center to the left while the car yelled at me to get the suspension serviced immediately; cutting the diff lock, not allowing me to disable traction control, and reducing the power steering. Sketch! But nothing I couldn't handle and still raced my wife in her Tesla.

Here is the after. It's Firestone so I had no say in having them go outside of OEM specs - not that I really want too as this is primarily a daily driver.

In the 30 mile drive back home I got to do a couple power slides and hit some turns. Car seems great and there isn't any additional NVH. So these are certified OEM+.

That's it for suspension (for a while). Will be doing exhaust next followed by rims/tires. Have a drift event coming up in May that will really test out these new suspension components (just doing the skid pad won't be doing the actual track).

Glad you got er aligned! Planning on a little more camber? A little might spice things up a bit. Even if just to get groceries ?

 

[Rensuhlo]

Glad you got er aligned! A little more camber will never hurt a sports car. Even if using it to get groceries ?

Or just let the man get whatever camber he wanted with the mods he installed?

As a car bowling aficionado I must disagree

There corrected my post to better suit what I meant - less literal ?

I’ve got a bit more on my MX5 and a crap ton on my Supra ofc. Neither have overly worn the inside tires. But they are fun cars and I like to be able to corner a bit more faster & stable. No criticism to Mr. Funk, just assuming (maybe wrongfully so) that he might like to drive the same. Ofc he can do what he wants ?
