try launching at a slightly lower rpm so the tires spin a lil less, i think that would help your 60ft also...but i do agree with above posted statement that you have lower times possible based on that weight and the mph...just get that traction solved
I have eibach Pro-kit springs w/ KYB GR2 shocks. Not really set-up for drag racing. I did have the front sway bar removed. I dumped the clutch on every run. I was thinking that maybe I should have sliped the clutch or let it out instead of side-stepping? Maybe it would have helped? I did launch at 3500k and it not get any spin but the car bogged and I had a 2.0 sixty foot.
It is a trial and error thing. You don't want to spin the tires too much but you want to stay away from the bog aswell. I would suggest that you play with launch rpm. You have 1500 rpm there to play with between 3500 and 5000rpm. You might find a sweet spot there. Your suspension does hurt you a bit but I was able to get a 1.6 with KYB gas struts and shocks and Ford Motor Sport C springs.
If you want to improve your track times, 4.10's are the ticket for you. Maybe even 4.30. I went from 3.73's to 4.30's becvause thats what my combo needed. Drives fine on the street and mileage was uneffected. Its a weekend toy so it didn't matter if mileage was effected though.
You should be going through the traps 6,000+ with that combo.
