Choosing an aftermarket subframe
I just introduced myself over on the introductions forum, but now I want to get to business. In searching for an aftermarket subframe for my 68 Camaro, I came across your forum and read several of the threads discussing aftermarket subframes. I have researched at least six different manufacturers, and I think I have it narrowed down to two in my price range.
The features I am looking for are;
Power rack and pinion steering (Preferably front steer to help with future LS oil pan fitment.
Modern suspension geometry (negative camber gain)
13" brakes
Swaybar
LS engine compatibility (Oil pan fitment and front accesory drive compatibility)
Prefer slightly narrower track and stock height (My current 17X8 wheels with 225-50-17 tires hit on the outer edge on larger bumps), I can go with wheels with more back space if this is not psossible.
Weight reduction would be a plus.
Reuse of TKO600 trans mount and bolt in subframe connectors would be a plus.
Chris Alston, Speedtech and Jim Meyer all looked pretty good, but they are currently out of my price range. (Note: If I determine that the either of the two I am considering will not meet my needs, I may wait until I can afford these pricier ones.) Fatman Fabrications is in my price range, but they use the Mustang II suspension which is based on 70's technology. The two I am looking at are Martz and Heidts Pro G. From looking at other threads, Martz seems to have an issue with flex, but that may be before they added the hoop bars that go to the firewall. Their suspension geometry appears to give me the negative camber gain I am looking for and I can maintain my stock height. Heidt's Pro G looks good, they narrow the track width 1/2 per side but are only avaiable with 2" drop spindles which means I may have to change wheels.
So, has anyone used the Martz subframe with the hoop bars and had flex issues? Has anyone used the Heidt's Pro G? How do you like either of these.
If you don't like either, what makes the other ones worth more money?
I am really hoping this group can help me make a decision.
