Guys,
1. Does anyone have any comments about swaping out the stock Kmember for the tubular Spohn version? I'm working on losing weight in the 3rd gen SPO car and wondered if anyone will acknoldge it is stong enough for road racing abuse.
2. Has anyone swaped over to the Rack and pinion sterring (Pinto) for weigh reduction?

3. What are the best headers for 3 gen vs. tranny combo for clutch fork clearence issues.
Currently use T56,LT1 version with Heddman standard not shortys.

Just need some quick easy responses on these topics.

Thanks

Kind of what Infernal says. With few exceptions, the aftermarket K-members are built primarily for the drag racing crowd. They do okay up and down and front-to-rear motion, but not well side-to-side. By the time you've gusseted everything and increased the structure enough to be strong enough, you're at, or above stock K-member weight. Stick with the factory K-member. Cut some lightening holes, if you must, and weld up all the seams, but that's about it.

I'd also re-use the stock lower control arms. You can cut that section out of the middle where there's places for shocks to mount, and cut some lightening holes along the leading and trailing edge (I've seen this done on some 3rd Gen C Prepared cars with success) and call it a day.

The Pinto rack is going to be too slow for you, probably. A couple of friends spent last summer fabbing up a new front suspension, including a rack-and-pinion, on their 2nd Gen Camaro CP car. After bending a couple of stock-type racks, I think they ended up buying an Appleton rack and using it. Even after a LOT of cad designing, they ended up increasing their turning radius some. Otherwise, it looks like it did well. They did start with a 2nd Gen K-member, for the same reasons as above.
