Racers look here to help a newbie -Thanks

1) you have to decide if you want to run a certain class with your car. x275,nmca,orsca, pro nostalga. and see what they allow for suspension's.
2) how knowlagable are you at tuning suspensions.
3) if just bracket racing at the local track go with a ladder bar with some good coilovers. very easy to setup and consistant
4) if its a dual purpose street / strip go with leaf spring or a triangulated 4bar with a antiroll bar, coilovers.
5) if all out race and you are willing to learn how to tune to your power level and track conditions go with a 4-link,antiroll bar, and double adjustable coilovers.

anyone of these rear suspensions are capable of getting you safely into the 5.00's in the 1/8 mile or the low 8's in the 1/4 mile

it just depends on how chassis savy you are at setting the car up and how consistant you want the car and how much MPH the car will run

a very good but dated book to read is a book by Dave Morgan.
