Whats The First Thing I Should Do For Traction

well im passed the stock suspensions limits, i ahve a real ahrd time cutting 60fts below 2.3s and 2.4s. its getting annoying! ive tried every tire pressure from 17-25, every launch technique, slipping, dropping. i can dump the clutch at 750rpms and it justs goes to 5200 and bruns the **** out of them, then when i grab 2nd it gets sideways a little. are drag radials the first thing to get?

Skip the DR's and get some aftermarket suspension peices if you are having problems. DR's are only going to take you so far

Also go somewhere and practice launching, don't just dump the clutch, even at 1K or whatever, you may just have to pedal it out.

I was spinning my tires awfully bad with my Firestones, 2.1 60" times and couldn't pull any quick.

Paid $140 a piece of two BF Goodrich Comp T/A Drag Radial (street legal)...and I'm positive I'm pulling 1.8 60" times or better. This mother F'er hooks. These tires are so incredibly soft that you won't even need to heat them up.

yeah thats why i think i should get some stickies first, cause all those suspension peices are useless if the tire wont adhere.

Tires will make the biggest difference in traction, dragracing or roadracing. If your car has the original suspension pieces, you might want to bring it back to OE quality and try again. Even with the same tires you might notice a difference. Technique also has alot to do with it when you have alot of torque. Try to feather the throttle next time. Choosing the RPM to launch is 1/2 of it. Throttle control is the other 1/2.

First thing is tires.

Then to fix the wheel hop you 'll have once you get tires that will hook up, a set of LCA lowering brackets, and some non-rubber LCAs.

I need to ask a question about this, and no I'm not trying to sound like a dick. I read this same statement in another post you had not too long ago and was wondering how you get wheel hop when your car hooks? At the start of last season I just had some radials tires, once I'd fry the heck out of them in the burnout box they'd bite, anything less and I'd get wheel hop. Once I got my DOT slicks, wheel hop was a thing of the past, never at the track or on the street. I guess I always thought that wheel hop was from the car biting and letting go-biting and lettign go, once the stickies are on, how is it going to let go-assuming everything is working correctly. I'm just asking becasue I've never had that problem once I got the stickies-and street tires after a certain point just went up in a cloud of smoke with no hope at all of hooking on the street, looked cool, but very boring to drive like that. Again, don't get insulted or offended, just trying to get this figured out for future advice.

If you're ONLY goal is too get better traction when launching, before following the tire and suspension advice ( which is all SOUND advice ) why not try a cheap trick that I and others have used in the past?

Buy one air bag. About $40. Install it in the pass rear spring...takes 30 minutes. When you get to the track, put about 18 psi or so in it and play around with the pressure...this preloads the suspension.

I've used this on more than one car at the strip, and the results are WELL worth the $ and effort...

My '80 Malibu with totally stock suspension and normal street tires cranked out consistent 1.9 60 ft times with this setup....
