Race Tracking Your Supra - Information exchange

I am planning on buying some track wheels 18” square and really wanted to avoid spacers by sticking with 10” width but now I’m thinking I will move up to 10.5 and use spacers like everyone else.

Also with a macpherson strut when camber is added the scrub radius will change, adding spacers will get you back to where it was.

I would think this only applies if you use control arms to increase camber rather than moving the entire strut as does the camber plate.

great. Thanks for the info. Ordered the verus plates and the BM spacers too.

Are the BM spacers hub and wheel centric like those GT4 beauties?

It would be both as the angle of the upright changes, so will scrub.

wheel size doesn't matter so much as design and offset.
Also, FYI, you can quote multiple posts at the same time. If you click on the "+quote" of each post you want to quote, then hit the "insert quotes" button. It's a time saver vs making multiple posts

the BM site said they were…

Turns out there is less than 10% difference btwn each of the softer settings on the Eibach bar and the first. You should not notice much of a difference cutting the last out. I have mine in the middle and the car is quite well balance

Found out all we need to do is use the “adjustable” endlinks ??‍and (when under compression - not in the air) the sway bars won’t touch the control arm. So you are right, I need to select that last notch. Met up with a good pro race buddy that said that along with dialing down (or is it up?) my Ohlins and make them stiffer. He was able to press on the front of the car and the back and could tell I was way too soft. Hence why I was getting rub front and back. He’s not working on my car & just a friend. But it made sense & glad he looked at it.

The end result after a weekend of really high speed right hand turns (drivers side). So I can adjust the height even more or… make her stiffer. Will be doing the latter and can go up in height, if needed. Also toasted my pads. I’ll have to get a pic when they come off for @Rocksandblues and see if I made the cut for maximum use ?

I knew this going in. Wife and I were doing double duty. Almost got two full days out of old pads and tires. Had a blast ?

got to see a Nissan Z. But that’s about all of them. No new ones in my area.

@racebuild are you aware of a way to increase the strength of engine braking?

Any1 using Dinan Monoball kit?

or SPL ones. any opinions if its worth doing?

Would need a tuner familiar with valvetronic tuning for a factory DME. Race teams are all on standalone, many with valvetronic locked out and using the throttle plate the conventional way.

what's the industry standard for windshield treatment these days? have used rainx/aquapel before, hoping for something more effective:

Didn't someone in the plethora of posts say that they're at the racetrack and their brakes intermittently weren't working?
I'm driving along and everything is fine but on some of the turns I just seen to have no brakes. The pedal feels fine, I'm just not slowing like usual. Very little power, not even coming out of my seat. It's costing me about a second or more per lap.

Like the pedal effort is high but no braking force? Has the car had the brake recall?

The brake pedal feels normalish. Maybe a little stiff. No vibration from ABS or anything, just like the calipers are locked out or something.
I bought the car with 1900 mi on it so I'm thinking no recall.
It's doing this almost once per lap. Cost me a pretty serious off into the dirt That may have cost me first place today.
