So on my red car I had really good traction after my engine mount install. Could launch it with fairly no wheel slippage and even when they were almost gone it still gripped good.

So onto the oddity my white car has problems with traction compared to the red car.. Pushing less HP nonetheless. Could springs contribute to this? I have no idea why the huge difference..

The Added weight of the CMZC Banner in the front might have had a lot to do with it.

J/K....J/K

What kind of tires do and did you have with both cars?

My guess is either the new car's tires are just worse or the springs are softer, allowing more rock toward the rear of the car, lifting weight off the fronts and allowing more spin.

Then again, I'm mechanically special ed, so don't pay me any mind...

Tires would be the first thing. You need to do a better job of discribing the problem.

Do you have an engine mount on your stormtrooper speed? we talking about the same crap ass oem tires or did they change them
on your new ride?

you have added springs and rims to this new car which I am sure have altered the performance a bit, but I would've
thought the car would be more planted with the springs. There should be less lurching as a result...

maybe jack can chime in as to any differences which his ride since his spring install?

If the tires are the "same" there is a difference between scrubbed-in tires and new tires. New tires have a residual coating of the mold release used to seperate them from the mold. Alot of racers/autoxers will have their new tires specially treated before they even get them to help get rid of that mold release along with getting the tires broken in properly.

Either that or you could just suck..... that's always a possibility too. :P

DAMN! Rough crowd. Speed have you been pissing everybody off again? Yes, your springs have a large amount of effect on traction. Weight transfer away from the drive wheels equals less traction. That's why the front drive sissies in Nopi have wheelie bars. Stiffen the suspension on that pig already!

Tires are Potenza somethings or others whatever stock OEM tires are. Not much more to describe about the issue everything is the same on the car but the springs and its making less power.

Gold and Tom great posts thanks guys so what would you suggest to fix it besides new tires :P Those will be coming.

do the tires just spin or do you have wheel hop? If they are just spinning than it is the tires.

How much lighter are your new wheels compared to stock? Would a lighter rim equal slightly more power to the wheel making wheels spin easier????

they just spin no wheel hop. Wheep hop would mean too much traction I believe? They grip then slip caue the speed then grip then slip that'd be wheel hop correct?


Yeah the tires just slip constantly if i push it even slightly hard.

Checked air pressures lately? They might be overly inflated. Sometimes tire monkeys just fill the crap out of them when mounting them.

Sounds like your car needs better tires.

Wheel hop is caused by suspension flex. The car or truck will actually hop and will not be a continous spin. This is real common on trucks. Next time you see a redneck spinning his tires, Watch the rear end.

Dammit Josh... details. Post effin' details. Be specific. The following things would help:

1. Do you have the same motor mount on the new car?

2. Is this just occurring in 1st gear? 1st & 2nd? ect.

3. What are the spring rates of the Cobb springs, and what were the rates of the stock springs. This is something you should have looked into before buying the new springs.

4. How much of a drop did you have with the Cobb's? How much travel did your stock suspension have to begin with?

5. Something you probably wouldn't have checked... but, are you hitting the bump stops when your suspension is compressed?


Any details would be great...
