Suspension Advice Needed, Front bars, shocks and rear springs. Options

[jmill]

Building a Street/Track car, think more track than street. The car is flared with 16x7's and 16x8's. Building a 2.4 6 with 2.2S p/c's and 911 front suspension. I need some advice on front torsion bar size, rear springs, inserts/shocks, and sway bar size. Thanks. (IMG:style_emoticons/default/beer.gif)

And what do you guys think about these?

911 M rear calipers are a good match for the A fronts. Tarett makes a good anti roll bar. I *think* Chuck Morland (Elephant Racing) sells bronze rear bushings for the 914.
Edit: Ayup, he does. $315 for the kit thru Pelican.

They are my second choice. Clint from Rebel said they had a kit in the works. It's similar to their fronts with the exception of a tube insert you weld (or lock with a nut) into the trailing arm. It seems like a better fix IMHO than relying on the poly to deform. I would think they might not be true to each other and bind a bit. If they don't come through I'll go with the Elephant.

You may want to go with a little more rear spring than 225. I settled with 250 to 275 depending on venue. And I had 19mm front torsions. The car pushed too much with anything less and that was without a LSD initially. No rear bar.

I'm a bit worried about that myself. Chris recommended 200 and so did Clint. I went a bit heavier with you guys suggesting 250 to 275. If I push I'll install my rear bar. If I get wheel spin I'll go to a heavier spring.

You'll have to excuse my ignorance. Whats the difference between the M and SC rear caliper? I don't know jack about 911 rears.

I'd bet Chris and Clint are more on the ball than any of these guys here. Greg has said 200-225 is perfect for a 914 with no rear bar. Since Greg is an actual race engineer for a big race team and has won nationals with a 914 that gives him a lot of leverage. Chris and Clint as well have shown they know their stuff.

JP, Randall, Me, Grant, are all guys with different opinions and life experiense but nothing really to show for it. Take what we say with a grain of salt (IMG:style_emoticons/default/wink.gif)

If you can find a rear caliper that has a bigger piston without going to a vented rotor you will be better off. Eric will know what you can do.

Remeber setup for AX car is a lot differnt from track. The reccomendations from the very capable track guys are spot on for track work. As much as I'd hate to admit it JP does know a bit about AX setup. So does Randal. But you are right non of us have ever accomplished sqwat with 914 at a national level. I can live with that. But I suspect JP will continue to delude himself into thinking he built the worlds finest 914 ax ever known to man. Curious have Greg, Clint or Chris set up a nationals winning 914 AX car? If they have I guess I missed that in the past several years. LOL!

But ultimately it all comes down to expereimenting. There is no single right answer. Driving technique, tire choice, etc all play into setup. I would budget money for a few differnt spring combos from 225 to 275. That should do it.
