Pure slicks -AWESOME TIMES MAN! I WANT SLICKS!
Im getting the FRPP tune with TONS of Tq down low, have race motor mount, sway bar, FRPP intake and Short shifter. thinking with slicks like those i can gte to 13.5's. what wheel did you mount them too? can we see pics of what they look like on the car ?
also "Pure" slicks or "cheater' slicks?
Never have used tubes in slicks.one more question: ive never ran slicks...i heard guys talking about using tubes in them ... is this what you did?
Man that looks sweet. any trouble with the stock clutch or suspension holding up? or took it like a champ?

Curious that 2.1/13.71 that says "PB"... what does that mean?View attachment 211793
First run of the day = 13.71 @102.67 (Too much air in the slicks, 15 psi)
Second run = [email protected] (1.80 60')
Third run, 1st round of brackets (win) = [email protected] (1.79 60')
Fourth run, 2nd round of brackets (win) = [email protected] (1.79 60')
Fifth and finally run (Semi Finals, lost) = [email protected]
As always only the spare was removed.

If not mentioned it's still OEM issue.
Dude, you are doing some cool sheit here, for sure. I would just like to point out, before you buy wider wheels: a wider wheel *will* not give you a bigger contact patch ~ all else being equal (car weight, tire pressure). It will only change the shape of the contact patch. It will make the contact patch more transverse than longitudinal.You actually want a 17x9 wheel -
I will be upgrading to a 17x9 wheel soon = more contact patch
Never have used tubes in slicks.
Unfortunately, it won't. I don't make the rules, physics does... I just do what I can to exploit them.Well sort of...
A wider will in my case will work better as it will extend the contact patch.
My slicks are 8.5 wide and my wheel is 17 x 8 wide.
A cheap fix for the suspension is drag bags or even pee-wee footballs. Anything to pump up in those springs and keep them from compressing too much. It made a surprising difference for me when I had my Cobalt.No clutch or suspension issues.
That said, I am looking to improve on the stock suspension tendency to lift the front end and squat in the rear at launch. That dynamic works great with RWD, but not so much for FWD or AWD for that matter.
Best 60' is 1.76 which isn't bad on the stock suspension and stock torque levels.
Lowering the suspension somewhat and going an inch wider on the wheels I hope to get down in the 1.6's and then the tweaking will start.
You're ignoring the issue of a tire under load and the application of lower pressure to slightly deform a tire for drag racing. I see where you're coming from as it relates to ultimate grip in road racing or auto cross, but wider tires properly sized to an adequately wide wheel sure as sh!t helps with traction.Unfortunately, it won't. I don't make the rules, physics does... I just do what I can to exploit them.
I encourage you to give this some thought, maybe even draw it out. With all else being equal (tire pressure, car weight) the only thing that can change is the contact patch's shape.
Here's an example (numbers are for illustrative purposes only):
If you have a narrower tire with a 3000# car at 15psi tire pressure you will have 12 square inch contact patch area - in a longitudinal shape.
If you have a wider tire with a 3000# car at 15psi tire pressure you will still have a 12 square inch contact patch area - but now in a transverse shape.
Changing wheel/tire width only changes contact patch shape - not area.
It's just physics, you cannot change the size of the area by changing your tires' shape, you can only change the shape of the area. If you want to adjust the size of area (larger or smaller) you adjust the tire pressure.
I've seen that trick used before, it's in consideration.A cheap fix for the suspension is drag bags or even pee-wee footballs. Anything to pump up in those springs and keep them from compressing too much. It made a surprising difference for me when I had my Cobalt.
