Highest RPM launch on Fwd street tires?

[fulanititoo8198]

I just changed my wheel setup from 205/40/17 over to 245/45/17 (Azenis). My launch use to be around 3500 which got me a few 2.2 60 ft's. The other night I played with my car a bit and found I can now launch around 4-5k with no spinning at all. It seems to good to be true but I cant wait to see what 60ft I'll get at the track. Anyways, what's the highest rpm you guys are launching on your fwd street tires?

Stock wheel size, it is about 3000 rpm...

I got a couple nise 4000k launches, most the 3200-3500k. I got some tires to try is time, 225/5016 yoks avs es100. I thinking with the rear shocks set at 8 and front set at 1, it sould took very well.

I wouldn't take it past 3500RPM, should be perfect if you nail it with the 245s.

Yeah, changing to the correct high alone probably helped you out quite a bit, not to mention going wider. How wide are your rims?

I recommend experiment with different rpms. 3,500 seems to work for most people, but you may do better launching higher.

I do about 5000K on my slicks

How much PSI do you run on your slicks and do you compensate for the open diff.?

Weld your center diff and get monster slicks. Rev limiter launch.

i run them on 12psi. but i try not to launch to hard of the line cause i dont want to break my shafts or my diff. But my best 60ft is 1.9 i hope i get a 1.8 next time up ill try to launch a little harder and see if i can break a 12.

Must be fun to launch a FWD that high, any wheelspin at all ?

8 inch width. Yea your right 3500 works but it seems I can do higher now.
