wheel hop

[IBustV8s]

i have a stock sr20det swap 240sx and im getting alot of wheel hop when i launch, but only at the strip. on the street no problem at all wat would be the best solution for my problem?

I just went through the same thing. First thing I would do is start with a fresh set of struts in the back and while your under there check your subframe bushings.

most likely ur shocks. they probably have no compression and ur floating on ur springs.

Are you asking this while running stock or semi stock suspension?

[compactfean]

Good condition, stock suspension will not hop. Why would it matter?

most tracks use a sticky solution to help higher hp cars gain traction..and most drag cars are set up so the rear end "Rolls" and squats lower to promote the "Dig" start of there run..our 240's with a independant suspention tend to hope unless the suspention is set up to counter act this as our suspention is normally tighter compared to a drag car.

Tighter suspension has nothing to do with wheel hop.... Wheel hop is caused by warn components. Period. I have owned my 240 for 10 years now and have got to experience the problems and solutions first hand......all the way back to when my car was a stock sohc auto, to the full built beast it is today. The only time I had issues with any of the car, it's because the stock stuff was wearing out (struts, bushings etc) causing loose sloppy conditions, not tight conditions.

you need to read the post all the way man..not just the bottom reply before you rebuttle...the poster said " he has wheel hop at the strip..BUT NOT on the street"...if his components were in poor condition..he would have issues dayly driving..not just at the track...please take in consideration all the information sire as both our answer's may be the corect ones..have a good day.

I agree and disagree. I agree that the strip creates different conditions and that your car will react very differently there. I also agree that strip only cars are set up differently than our street cars. I disagree that tight independent rear suspension is the cause of track day wheel hop. In fact if you visit the camero message boards you will find that the irs in those cars is set too loose at the factory and needs tightening up to reduce track day wheel hop, corvettes are the same. Older leaf style suspensions on drag cars are set up to "squat" and "dig" at the beginning of a run but the suspension technology is so different its like comparing apples to oranges.

thats a Camero sire...not a 240...the stock curb wieghts are way different hence the wieght transfer allso...i drag my 240 from time to time and have to adjust my settings to full soft in the rear or i hop all the way down the track.

I think your missing the point. Your saying that because we have IRS that our cars are too tight. That is false, YOUR car may be too tight but 240s in general are too loose. Oh, and if your hoping all the way down the track your doing it wrong, ease up and let your tires catch.

I used to neutral drop my auto 240 at 5k and no wheel hop. I didn't start getting wheel hop untill last season. Replaced the struts and problem solved. Since my car is a drag car I have used the supra/camaro/vette concepts for my suspension and have been rather successful. (2.0 60ft on street tires)
