Default How to improve 60 FT times?

What do you guys reccomend to get a better 60 ft time? I have heard people discuss adjusting pinion angles. Does this really help? If so, how?
Im ready to just put a big ass slick on my heep and call it a day....lol, I know there is alot more to it than that.

Big slicks wont do much with a poorly working suspension. Tell me your current setup (hp, tq, launching techniques (Any 2 step?), tire, suspension). Tell me your current 60 ft's. Do you have any video of your car launching? Give me as much of this info as you can and I'll get ya going.

Your suspension, tires and technique will always dictate your launch. Clutch drops are not going to get it done. Post some info on your 60ft times, ET/trap speed and also suspension/tire setup.

Well I'm going to guess its a street tire then, no DR or Slick. Remove the front sway bar, air up the front tires, lower your rears to like 30lbs and just spin them over once or twice to clean them off. Change your launch method. Try different things that do not shock the tire as much. Slip the clutch. Lower the RPM, ect.

If you have a real tire, I can help you with suspension setup.

Street tires on your car with the torque you have you would be doing good with a 2.0 60'ft like posted disconnect sway bar maybe even a little lower on tires say 23-26 psi too low will take away from tire footprint when car squats on launch. DR's would make a .2 .3 difference on a stock suspension car. You need weight transfer to get the rear to bite. I got a 2.0 on 215/70/14 old bfg street tires with a spool and 4.11's my 67 weighs a few hundred less than yours but you are making more HP than i was at the time. Next trip was 3,89's 255/50/16 DR launching at 3k and the car dropped to a 1.79 60ft. This was still with battery up front and no traction bars.

What tire preasure do you guys recomend on a 275 M/T dr? I had the most success with 14-15 lbs. I worked my way down from 18lbs. Got my 60's in the 1.70's but I know theres more left in it, just need the practice

Need to check your contact patch, do a short burnout just for some heat in tires.
On a clear Does your car squat real hard on launch? Do you have a vid or photos of a launch? They can help alot.

IMO having all the suspension in the world with street tires and they will still go up in smoke with your et's. The best bang for the buck if you really want lower et's and visit the track often is an extra set of rims with sticky tires, slicks being the best and DR being ok. If you plan to stay on streets than dont expect anything better than a 2.0 60ft.

All suspension and no tire or all tire and no suspension all equal the same thing. Compromise... The key is to find a balance IMO. Street on DR's will be different than a track only car on slicks. This of course does not answer the question as you may want it.

Trial and error, test and tune... Thats the honest answer.

Good control arms and a nice set of M/T drag radials will get ya in the 1.60 to 1.70 range if you are a good driver. DRIVER IS EVERYTHING!

+1 on the driver's mod!

I will be going to E-town next month, with my limited mods and street tires. This will be my 1st time running, and don't expect a nice #. Hell, I'll be happy if I can hit a 14.0 like a stock manual Gt should!
