That being said, where can you buy taller than stock bumpers? i've got stock ones on my cars, but could use taller ones.

I then put traction bar snubber and as many washers as possible on the lower control arm to answer another post about weak drag race torsion bars.

You can also fabricate some spacers that will work. Brian Dunnigan That is what I have on my 1969 Dart. I limit travel to avoid excess wheel stand. I bought some nice traction bar bumpers and cut them to the length I wanted. Then on each track day, I put between zero and 0.437" of spacers under the bumper to set the amount of front end travel and weight transfer I need for the conditions. A lower torque/horsepower car will want all the weight transfer they can get (short bumper), but a higher power car doesn't want to be on the bumper. 1993 Daytona, 5.50 at 130mph (1/8) 1.19 sixty ft (PG).

They also sell shorter bump stops too. 1970 Dart Resto-Race Project 1960 Dodge Dart Seneca Dual Quad 390 Poly
