Subframe options for stock sub aftermarket parts?
 

I was talking to DSE about a new sub, but I would not be able to use my Speedtech A-arms, hotchkis sway, and Willwood brakes and spindles. Are there any other options for subs out there that I could swap my parts onto and still fit a wider front tire? Thanks.

Speedtech is the perfect solution for you. And since your both in Canada.........

the Speedtech frame will work.
have to upgrade to rack and pinion, and steering shaft kit and coil over shocks. maybe headers and away you go.

I am running a BBC with some 2.25" Lemons race headers with my stock sub. Any issues with those on a Speedtech sub?

My GUESS is the header would clear, but I would not promise. I am sure Speedtech won't know for sure either. You may have to modify a tube or towo on the driver side.

Sounds like a winter project

Have you thought about reworking your stock sub.With a little bit of work you can fit a 9.5 wheel up frt.

What kind of work does that include?

If you use a unisteer rack & pinion you can notch the outside parts of the sub frame by a few inches on each side.We found our unisteer rack on ebay under a company called fatrodder.about $595.00 plus shipping.

Its about time these ""afthermarket"" companys, wil divelop stuff for the pontiac engine mill insted of ""ALWAYS"" think on chevy engine blocks only. Pontiac hase a there factory block , but also 4 ""afthermarked"" blocks and more then 10 diferend aluminum heads to choose from!!.

A serius wake up call is called for , There is also no rack and pinion for pontiac powers cars, yet there are plenty brands making them for chevy!! shearing that marked.
One of these companys should step up!!.. funny thing is speed tech is advertizing a afthermarked ""firebird and transam subframe"", yet it sais no modifications hase been done to ecsept the pontiac engine. how lame is that!!!!!

Any pics of a notched subframe?
