Hello
Sounds like a weight transfer problem! What type of spring and shock combo are you using? Might want to look into a 275 or 300lb front spring and a set of adjustable shock. Below is a link to show you what all UMI Performance has to offer.

any advice or links to what I need in like a package... still on stock springs, struts etc......

 

Sounds like you have most of the right equipment....give me call here at the office and I am sure we can get you going the right direction

 

I would suggest going with a set of front coil overs in the front. And seeing how you are using a aftermarket rear I would suggest staying with the factory rear spring and go with a adjustable rear shock. Unfortunately there is now kits.

Assuming he has stock springs and suspension, do you really think that those 275 lb springs are going to dramatically change his launch? I mean he changed a ton of parts.. anywhere along that way it's possible he may have something set improperly.

I'm pretty sure that you gotta adjust your input when you go to a higher gear like 4.10. People who have gears at my races say that I should stick with my 3.42's because with my 400 hp I'll be all messed up with my launches.

I've heard the torque arm pinion angle can make your launches worse depending on what it's set to.

I'm no drag expert.. but I figured I'd toss ideas out there. You hooked well on stock springs and then changed a ton of parts but left in stock springs and didn't hook well. Seems hard to believe that going from 293 lb springs to 275 is the solution to the problem when you did fine with stock springs originally.

 

thanks so far guys for the input!

 

Ditch the relocation brackets if your on the stock springs and set your pinion angle -1.

 

No Problem! If you have any other questions feel free to ask and I will be more than glad to help!
Thanks
