Rear suspension... HeLp

[SixFourDart]

I have a 69 dart with a factory 8 3/4 and 9 inch slicks. I plan on building a much larger motor for he car. I am currently running s/s spring and a piñon snubber. My question is how much power can a 9 inch slick take and what is the best rear suspension to help plant the power. Guess that's two questions.. and feedback will be appreciated.

stock eliminator cars (new mustangs) are running high 8s on 9 x 30 slicks....

8 3/4 ....depends on weight of car...transmission...manual or automatic...transbrake yes or no...
if you have to buy new axles...spool ...ring and gear for the 8 3/4....might as well spend your money on a dana 60....


alot of cars can run fast with caltrac and mono leaf springs....ladder bars and coil over shocks also can be installed....

Do you have an adjustable pinion snubber?For best results 3/4 inch from the floor.

My buddy ran into the 9's before his 8-3/4 broke in a all steel 69 Dart with a Indy headed 500 in RB. Full interior. He did run a larger tire. Just sayin the 8-3/4 lived a long time in the 10's.

It was all done on SS springs.

Look into the racers forum where there is a current thread about 60' times on SS springs going on. Others pipe in about there suspension.
