How do I get my 60ft times down???

[Mean88]

Best time is as follows,
[email protected]
1.90 60 ft on 275/50/15's side stepping at about 4k

Suspension is as follows,
hpm megabite jrs lowers only (control arms set in bottom hole for drag)
lakewood 50/50
no quads
stock front suspension, aside from removed sway bar and poly urethane bushings

With my mph and current 60 fts, I think I should be able to drop 3-4 tenths more yet, what do you think?
Thanks

What are these 275/50/15's, drag radials or regular tires?

Get some slicks or lower the tire pressure if you have drag radials. I run my Nittos at 15 PSI, hooks decent for a drag radial.

That may do it. I just put in the Megabite Jr's a few days ago, but set to the top hole and it made a difference. What about uppers? I have the megabite uppers comming when they get off backorder. Maby some 70/30's or 90/10's up front for struts?

I am just wondering if I shouldnt switch to the upper hole too. I am running 14 psi and a good heat up of the tires before launch. I still think that these things should get me 1.7 60's, dont you?

I would try that. Dennis at Motorsport-depot, the guy I bought the Jr's from told me that which hole depends on application. He said the lower hole is for cars near to 500HP, but for an application like mine which is closer to the 300hp range should use the top hole because using the lower hole (135% hole) you get more lift out of it but after that the rear end is going to drop back down making you loose traction, you have to have enough rear end tq to keep the rear end lifted. Really you don't want it to lift at all, jsut stay level. On the 85% level (top hole) I have noticed that now the rear end stays perfectly level durring takeoffs, doesn't dip at all anymore. All the power goes straight ahead instead of compressing the suspension. You don't want energy going into lifting half the car either. You want the power to get the the ground and shoot you forward.

I wonder if springs or upper control arms would help? My car sits with the front really high and the back sits really low. Looks silly having 4" between the tire and the fender in the front and 1'' between the back tire and fender. These are stock springs.

I've heard that it's good to change out the springs, the stock ones are tired. i'm thinking they compress to easily.

...But I don't like how the Eibach Pro springs ride, my truck rides better than that, my bro has them on his 87GT.
