Best ifs kit? rms, hdk, gt suspension, or magnum force?

There certainly are a lot of variables......and it is a balance.

I think some are confused on why builders modify the spindle....check the websites. Is there ANY mention of bump steer adjustment in their instructions?....NO!, simply bolt it on....much like you would if they made a tie rod end long enough for the geometry THEY are working with

I would be surprised if, other than the serious racer, most "fine tune" for bump steer. When I utilized the modification years ago, it was more to SET the tie rod angle where it needs to be in relationship to the rack and LCA pivot location for minimum bump steer.


on the slammer models....the motor is not raised, the chassis / car is dropped....which, BTW require different pivot points from the standard models.....but the look is awesome.

I realize the the spring rate does not change....a 400 lb spring still takes 400 lbs to move it 1" regardless of pre-load setting, but when excessively cranking up the pre-load to. raise the ride height, it also shortens the spring and IMO sure makes the front ride stiffer. You can be your own judge. Try this, take a spring out of a ballpoint pen and compress it 50%....now squeeze it...feel stiffer?

just some things to ponder on.
