Spring on the stability!

PNYXPS66 · 03-19-2001, 09:53 AM

I'm building a 79 coupe for everyday running with a little extra spunk built into the factory 2300. Would it be a performance advantage to replace the springs with springs for a V8? How about stabilizer bars? Any other tips for improving handling on the old fox bodies? Also, anyone know if they make different gearing ratios for 6.75 rear ends? Or are they too weak to bother with?

I have a 79 Pace Car that I have fixed up for handling.
First thing these cars really need to handle is chassis bracing - subframe connectors, K-member brace, strut tower bar.
After that replacing all the bushings with polyeurethane, and changing the springs and shocks/struts would be a good idea.
Putting in V8 springs would probably make your car higher in the front since you are lacking 4 cylinders.
I don't know far you want to mod the car, but the next logical mods would be control arms and panhard bar

Look into springs, that will help. BUT you gotta be careful, cause these are rated for V8 weights.
Racer Walsh carries a lot of parts for 2300cc racers. Try them.

Panhard Bar? I'm not familiar with the term. I understand K-frame and strut tower bracing. Since, understandably, the V-8 springs add lift to the car, would air shocks for the rear be a good solution to assist with leveling the car? Theory behind this is when the car leans out in a turn, the pressure will increase (moreso than a standard shock mechanism that works to stabilize internal pressure)to counter the gravitational force thus increasing pressure on the ground; adding traction and reducing the possibility of skidding out. What do ya think? Talk me out of the idea.

The panhard bar attaches at one end to the frame and at the other to the axle. Prevents lateral movement of the axle during hard cornering and acceleration. Also reduces the bind in the 4 link suspension design.
Probably best to get springs that are made for the 4-cylinder. I believe Eibach makes a set.
