I want to see what a 1LE with 315/295 cup 2's and minor bolt-ons can do!

[bpang1234]

In my 2SS, I just got 285 Front and 305 Rear (Michelin Pilot Super Sport) and I will tell you that the difference in handling and response is HUGE.

1. These Michelins are WAAAAAY better performance tires than the stock Goodyears...just straight up better tires even if I had went with stock sizes (I have run these tires in other cars for the last 5 years now).

2. The tire sizes I have are what the 1LE is coming with...the 40mm bigger fronts make the car react to steering input much much much faster, it is as though the car was meant to have them. The rears help the car hookup a lot easier and of course help with overall lateral grip.

Of course the 1LE will still be faster but I believe the tires are where the biggest gains are...that and maybe the e-Diff.

MPSS do not come on 305's only 315's

BMR lowering springs - camber and tow. square stance wheels and tires (285 front and rear on 19's - micheline PSS's.)

Looking to take it back out October 8th and will report back.

So I took the car out yesterday after doing the above.

We got 2.5 degrees of camber out of it, reverse tow, etc. 285 michelin pilot super sports front and rear - and 1" lower.

In a nutshell - if feels like a different car.

Like seriously - why dont they do this from the factory??

I've only taken it on open roads - but I pushed it hard and it was way more hooked up - way faster on turn in - even road better - which I attribute to the tires.

I'm taking it to the track this friday to flog and can't wait.

Looks good. What size tire did you go with, front and rear? Roughly how much did a set-up like taht cost? I'm debating between 1SS and 1LE myself.

I think I'm $4,700 all in.

MMR flowforged wheels. you can go cheaper on wheels - but they'd be heavier.

Micheline Pilot Super sport tires 286/35/19. these tires are also not cheap. you could probably buy the tires that come on the 1LE for less than these

BMR Lowering springs

The race alignment is really only needed if you're tracking the car - or really flogging it in the corners - but that was relatively cheap.

Not sure if you checked or not before you posted.

I know you fellas are all talking about the V8, but for the sake of information: I have a 1LT with the HD brake and cooling pack (so V8 front brakes and cooling in a nut shell) also have the RS package tires (the goodyear run flats) I've also found that the brakes will.over come the tire traction without much effort... And this is only on the street, I'll be investing in better tires (and wheels ) before i bother with the braking system.

Check this out. Car & Driver tested back to back a torque vectoring diff and not back to back. They say how the car feels to the driver is the biggest benefit. But there is some track time improvement. Some have claimed a slight acceleration benefit, but I am on the fence about that. Out of a corner, yea, but straight ahead considering even traction between the tires, like in the 1/4?

I think what you are looking for on the track is better heat dissipation so your braking does not deteriorate over mutilple laps. Not outright stopping power. And better braking parts can improve brake feel so you can adjust your braking inside of the antiskid or tire traction limits.

Well I'm hoping I'm right, If I get better tires on my 2SS with MRC I should have a decent street / trackable car that the wife can still drive it when needed. Maybe I'll add some 1LE suspension upgrades to my A8 2SS when they come out and end up with an automatic 1LE wanna be.
A few have said that tires can shave 2 or 3 seconds a lap and do better times than a C6 vette with the same tires. Thats good enough for me.. I'm happy..

Looking forward to hearing how this comes out, but you don't want tow. That's a ride back to the pits after something goes wrong.

You're adjusting camber and toe.

Fix the tow and don't forget the breaks. LOL

I completely agree with this. In addition, I wish GM had done the SS with a 20x9.0F/20X9.5 setup. The 8.5 front wheel width kinda sucks for tire setups. This car needs a little more front grip. A 255F/275(or 285)R would have been really nice. BUT, I get it. The LT comes with 20x8.5 all the way around and it's cheaper to use the 20x8.5 up front...

In respect to the tires being a limit. The last track day I did, I was in the 2nd from most experienced group (open point-to-pass all around the track), there were a bunch of C6 'Vettes and a S197 5.0L Mustang with Pirelli take off slicks (maybe they were Conti slicks...). My car was stock, apart from added front camber, RBF600 brake fluid and Hawk HP+ pads. I tried to keep up with the 'Vettes in the corners and just couldn't. The car seemed very capable of going there - very stable and emitted a sense of complete confidence; however the tires would just give up. I constantly had a battle with the Mustang. Guy was a good driver from what I could tell. The Camaro kept up with him fairly well in the corners, but any time I began to really creep close to him, the tires just started talking way too much and begin to let go. On the straights, that Mustang could not keep up with me. I had to let fully off the accelerator, completely, quite a few times so he could pass (it's just a track day and I'm not going to be one of those guys and try to fight a fight in the corners that I can't hold out - that's just annoying).

Car needs proper tires. The Goodyears, on a road course are really not bad for a factory offering, but in autocross just DO NOT get hot enough to let the car do what it can. I'll be doing Conti ExtremeContact Sports (DW replacement) for a DD tire, trying the Nexan N FERA SUR4 in my regional autocrossing and Bridgestone RE71R's for Nationals.
