DRAG WHEEL/Tire setups

Normally you want weight transfer in the back. But that weight transfer does you no good on drag radials because it reduces your contact patch to nothing. Example... If I do a rolling second gear burnout, the patches on the road are about 2-3" wide. My tires are 315/30/18. With stock shocks my car squats a lot, and to make it worse, I'm starting with crappy control arm angles by being lowered a lot on springs, causing the camber to pull in even faster with every bit on compression. If I put stock springs in, I would get more contact as my control arm angles would be better. If I put in real hard shocks, it would get better yet, as there would be less compression to cause camber.

Starting at positive would be ideal, especially if running all stock suspension and soft slicks... But nobody here is going to do it... It's too far into the drag only realm.

What I'm saying applies to this car and this car only (and 350z). Not all IRS cars have this problem... But this is why you don't see many fast Zs. It's rare that a Z owner is committed enough to go to full slicks and small wheels/brakes. But without that.. 1.8-1.9 60' is all your getting. There's tons of 350zs that have had the power to go single digits... You can probably count on one hand how many have done it.

I stand by my statement. A 600 h.p. car with EVEN JUST SOME traction prep. doing 1.8's/1.9's = sucks......

I don't think I EVER talked about street tires??? WEIRD?????

I was referring to the person that owns that 600+ H.P. car. Also people can't just say that traction can NOT be gotten by a 370 Z. That's crazy, there are cars including ZZZZZ's with much more H.P doing 8's & 9's at the track

OF THE TOP OF MY HEAD.

VINNIE TEN with their boosted car are/did do low 9's. That's my point! 600 H.P. is great but you have much more powerful cars & ZZ's doing 1.4's, 1.5's & I found NO PROBLEM, with my nothing of a car doing 1.6's ....... So fix that problem, don't say we can't.

By the way, 3/10's gain at the start 60' = apx. 5/10's at the finish line!!!! FACT !!!! APX. maybe more????

But yes, with a dedicated drag setup, proper alignment and slicks... ya for sure these cars can hook up great. Its just that its not what people in this community want. They want a full street car to hookup something closer to like what a vette or a viper can do on street tires. They can do it because of their different suspension profiles that do not camber 30 degrees when you try and launch!

If we can get the typical 60's down to 1.7-1.8 on normal 18" drag radials... it will be epic for the 370z scene because all of a sudden we will start seeing people get more excited about drag racing. As it stands, its really damn frustrating to even bother with how poor these cars hook up without full slicks. We need solutions that dont involve changing the rear brakes and putting on 15-16" wheels... and suddenly we will see a greater number of Z owners taking their cars to the track.
