1. question is can i install the SFCs with a broken spring or does that screw things up? Because ive read that the car needs to be level and equal weight on the tires.
2. Ive got the Hooker 2055s going into a 3" pipe (cat delete) going in a 3 in catback im wondering if this is gonna cause any problems?

 

i think it might be a smart move to spend your time and effort in having your car in good repair and safe operating condition before you go modding it

 

thanx for the advice and i will be getting new springs soon. but the questions still stand without answer.

 

You need the car on loaded suspension before welding on SFCs. Optimally, you should have the frame checked and straightened first, as well.

 

alright thanx so what your saying is that i optimally should get the springs done first but it would be alright to do them. how about any problems running into my ypipe and 3 inch piping running from that?

 

No, that's not what he said, he said you 'NEED' the car on loaded suspension, not 'i would be a good idea', The optimally was the frame checked first.

 

Here is what you SHOULD do:
Go get your frame straightened first.

Here is what you MUST do:
Put new springs in the car and load the suspension before installing the subframe connectors.

 

It is not necessary to have "the suspension loaded" when installing SFCs; but, what ABSOLUTELY IS necessary, is that the frame be held straight. The suspension doesn't even have to be on the car at all. In fact, when mine were put on, it wasn't; the body was bolted up to a race car jig, and the SFCs were installed with it rigidly held perfect like that. Then the K-member and the motor and the rear end and the interior and everything else, was added later.

As far as interfering with exhaust, that depends greatly on what exhaust you have, and what SFCs you use.

 

spohn makes a great product for sfcs and i've never heard of any fitment issues with them

 

Interesting stuff here. What is a race car jig? Similar to the machines used to straighten the frame?
