Cayman vs Supra tracking cost

[romanLegion9574]

Can't really speak to Cayman Ss and the like -- haven't spoken with anyone who tracks one.

A buddy of mine has a 981 GT4 and his main concerns are tires -- tires for the stock 20s are expensive (and due to sizing he's basically limited to Cup2s). Downsizing to 19s is possible, but there's very little clearance from the brakes (like 2-3mm based on some pictures he sent my friends and myself). Maintenance like spark plugs and air filters are also a bit more work considering the engine placement, if that matters to you.

Beside MSRP, running costs are a bit cheaper in the Supra since you can downsize to 18s and have more variety in tire choice.

At my home track (the Ridge), I've seen Supras with alignments and 200TW tires running 1:48s which is in the ballpark of GT4s on 200TWs. Ultimately, the GT4 does have the higher performance ceiling, but you get pretty damn close for half the cost and much less upkeep.

Having gotten a ride in my buddy's GT4 during track days and in an instructor's Supra (on 200TWs), I've never experienced the Gs the GT4 pulls in the Supra, but the Supra's weight distribution allows it to follow the same line mid-engine cars take around the track.

Porsches are fantastic! It’s just a price point that’s not realistic for me - to get out there, track often, with less $$$ guilt. Plus I like to break stuff ?. Replacement parts are much cheaper on the Supra.

Every car should be following the same line- well, except Miatas.

It's more that mid-engined cars and cars with a closer to 50/50 weight distribution rotate a little better through the carousel and coming onto the kink before the main straight, so they can get on power a fraction earlier since they don't wash wide. Having been on the track with both the Supra and GRC, and having ridden with my buddy in the GT4, I definitely notice that I have to adjust a little for the GRC's understeer.

Sorry for the confusion.

Still the same preferred or optimum racing line. Some cars can't hold the line at same speeds, but that doesn't mean the preferred line changes.

you can still get variation of the same lines based on the caracteristics of the car (front or rear limited, type of power delivery, etc).

In my GR86 I rather use more of a "U" line to carry as much speed into the corner as possible since the car is power limited. In the Supra I rather use a "V" line to get back on the power as soon as possible as the car is mostly rear limited.

In a "U" shape style, I'll typically have more traditional line when corner entry is on the outside, you hug the apex and let the car track out as soon as possible in an effort to get as little steering input as possible. In a "V" shape style, corner entry (and corner in general) is going to be a little wider and get a sharper truning point at some point during cornering to get back straight and on the gas as soon as possible, sometimes even missing the apex a little. That works well for cars with a lot of power and a great frontend, like the Supra.

Same team attitude here... But that is what I was referring to Miatas a la momentum cars. Yes, they do have different lines in certain but not all turns.

All cars above momentum, regardless of balance should TRY to hold to the racing line. Some will push/wash out.

We too- at my home track have a tricky corner that has 2 very apparent preferred lines. The Miata and momentum line is inside all the way around. Not "v" for us but kind of a "D" shape.

But yeah- I think we are saying the same-ish thing. Wasn't trying to be a a$$. Have a super weekend!

for sure not trying to be an ass as well haha, but racing line is always fun to debate. Even at my local track after 10+ years I still try new things every year after discussing with other drivers!

But you are right, what I refer to as a "V" line is often closer to a "D" line.

At times that’s even more fun than chasing lap times. Driving different lines, overtaking, getting passed & following them. Especially under always changing track conditions. Makes ya appreciate watching (or experiencing) a pro driver go around the track with lots of traffic, forced to go offline and not loose tons of momentum ?

Speaking of cost, how much do front brake pads cost on a Cayman? These are the biggest consumable expense for me. In the beginning, I was getting by with Hawk DTC60s up front ($210 per set). Got faster and started scrubbing more tire. Moved up to project mu 999 ($325 per set) and loved em!! Unfortunately they’re on back order and still waiting. I’m happy with the rear pads (Hawk DTC30), inexpensive, wear very little, good bite and not an issue.

Question for Bob @Rocksandblues:
CSG has two front pad flavas for our cars, expensive and incredibly expensive. The pricier one is what I prefer on paper. Says they are progressive vs linear (or digressive). Have you tried both (C21 and CE2)? If so, is it worth the extra coin for the CE2? Buying my backup goods for the upcoming season. Thx!

 

[Rocksandblues]

Have used c21 for 2 seasons and have tried lots of pads. They are the best/consistent pad for agressive track I have found so far. At some point I will upgrade brakes to 6pot.

the new endurance pad compound gets good reviews from the guys that use them. I have not tried them yet.

yes csg expensive. But worth $ being able to stop from 157 to 45 every 2 mins for 30 mins with out fade or fail.

I can‘t wait! I’ll buy one of each and let you know then. Thank pal
