rdsk8ter Posted September 14, 2008 Share Posted September 14, 2008 I have done alot hurs and hours of reading I cant decide do i need a solid rear or will a r230 work. I will be right about 700ponies at the wheels 98% of the time the car will be on the track (straight line) Are there links here I am missing? Thanks for the help Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted September 14, 2008 Share Posted September 14, 2008 A true 700HP at the wheels will require a solid rear IMO. It has been done IRS but it's probably not the best route safety wise. Quote Link to comment Share on other sites More sharing options...
Six_Shooter Posted September 14, 2008 Share Posted September 14, 2008 If you're going to be (almost) strictly drag racing, I'd swap in a solid rear axle. The contact patch between the tire and track surface will not change on launch, giving the highest amount of traction at the launch where it's needed.

gregkring Posted September 14, 2008 Share Posted September 14, 2008 98% straight line would qualify it as a drag car, so build it like one. Four link/backhalf setup. Plus to even go in the 10's in a Z car and be NHRA legal requires you to get the car ridiculously light, somewhere under 2200 lbs if I remember right. With that much horsepower I assume you plan on running well under 10 seconds, which will also require alot of cage work as well. So build the cage and rear at the same time. You will basically be building a chassis car with a Z body on it. Quote Link to comment Share on other sites More sharing options...
