Those SUPERCAR 3R look decent. Too bad they don't have any suitable rear sizes for the C63.

SRG_C63

you have to take 265/30 19 all around on 9,5x19 like me. Steering improving is genius!

Jasonoff

I'm a ways away from stuffing larger meats under her skirt.

You mentioned -3.8° front camber. What's the rest of your specs?

I was planning on giving this a try as a starting point.

F Camber: -4°
F Toe: 0

R Camber: -3°
R Toe: 1/8" Toe In

SRG_C63

What do you mean? 9,5x19 fits great around the car without any bigger mods.

Dont give it to much Camber in front. -3.8 is too much for me. I will lower it. -3.5 front and -2.5 rear would be great.
If you only track it, give the front a little bit toe out. Back Toe in is good.

Jasonoff

That means new wheels.

New wheels will happen when I chop out the rear fenders but that's so far down the priority list.

You saw the interior pic right? lol. This is a track only trailer to/from.

What suspension are you running?
Why are you reducing from -3.8 to -3.5? Too much inside wear on the track or because you still drive it on the street?

SRG_C63

There are enough people in Germany who still drive such a car on the road

I drive a KW Clubsport. But now I change to a KW Competition 2a.
Tire temperature measured and wear pattern viewed. With the Toyo I do not yet completely drive off the outer flank. The tyre is not fully used. Same in the back. I reduce from 2.7 to 2.5.

More camber is not always good. You have to look at the tire temperature, air pressure and then the outside flanks when you drive. If there is still space up to the flank, reduce the camber until the complete tyre is used.
In addition, too much camber is extremely disturbing when braking on the straight before the corner.

Jasonoff

Yup, I fully understand how it all works. A 265 behaves quite a bit differently than a 245 though. Maybe I will start closer to -3.8 in the front then.

The problem is, there's just no real data to go off for this particular car with nearly 600lbs removed from it. The starting point is essentially guesswork.

Thats exactly my spec.

sventastic82

Really positive Toe in the rear? How come?

BLKROKT

More stable particularly when braking into corners

sventastic82

My question was more related to an argument Jasonoff and myself had in a different thread.

Jasonoff

Because I don't want any toe wear from all the throttle stomps

Don't waste your time... Toyo R888R is what you want. If you want more grip then you'll want to go with an actual slick.

Jasonoff

A couple easy shake down laps from last week. Had a buddy follow to watch how the suspension was performing. Didn't have the gopro set properly so the contrast is bad.

Still had street tires on the rear. The KW Club Sport were set in the middle for rebound and compression out of 21 clicks. I have since gone 2 clicks + compression in the rear and 4 clicks + compression in the front to see how that feels.

I couldn't get my hands on trofeo r rears unfortunately so sport cup 2s will go on. Other than barely much grip in the rear with the PS4S the car was surprisingly stable

Stringtheory

Very nice. It seems you are very close to 55% fr 45% rear balance, did that change as you lightened the car, or was this the same approximate balance as stock?

Jasonoff

It stayed pretty much the same after gutting it.

sventastic82

If you keep driving like that, those rears will last another three seasons.

Jasonoff

Wanna race for pink slips?

sventastic82

sure, Let me get my hands on a Honda first.

Jasonoff

No deal, I need YOUR car for spare parts.
