Tubular K-members and rear swing arms, who wants some :)
Ok you drag racing fools, I'm dropping an extra cradle (front and rear) plus the rear swing arms off at Holzman race cars to get a price on making these in large qty.
I have no idea what the price will be yet or when they will be available.
Holzman Race cars is who built the cage in my car. They have been building race cars forever and do top notch work.
I need to know who would be seriously interested in getting these parts. What I'm going to have him build jigs for are:
Tubular front cradle
Tubular rear cradle
Tubular rear swing arm (will allow for wider tires)
I don’t know if any of you have weighed the rear cradle and swing arm but they heavy bastards to say the least.
Thanks
Chris
I'll be posting up photo's in the first post so you dont have to dig through all the posts.
I was going to bead blast them and throw some paint on them first, but here they are.
This is the passenger side one, the driver side looks just like it.
All jig located and tig welded.
They will come with bushings to locate the hiem joint in the mounting bracket to give the most tire clearance possible and still be a bolt in deal.
By doing the tubular arm and the hiem joint position at an angle in the bracket, you'll gain about 2" of tire clearance.
The control arm you see here still has the coil spring mount. The ones I will be running will not have the coil spring mount.
The coil overs will use the stock lower mount so that the control arm can still be used with stock shocks if needed.
The upper coil over bracket will be either weld on or bolt on by drilling some holes through the frame rail.
Here is what we are doing for the mini tub.
We pretty much went with the largest mini tub possible, clear to the frame.
We took out the coil spring mount too.
This is the biggest mini tub you can do without cutting into the frame rails.
What's the ballpark figure for total weight savings with a front/rear setup?
Not sure yet. The cradle should save 20-30 lbs. I'm going to look at using a different brake set up with an off the shelf suspension like a Mustang or Fbody set up too.
Might need to do 2 versions, one for maximum weight reduction to use a totaly different suspension and one that will bolt up to all the OEM parts.

on the front are you gonna leave it rear steer ? or maybe consider a front steer ? id rather have front steer and use a camaro oil pan , better for drag racing to keep the oil in the back
if i was staying IRS id love to get better arms , but going SRA kinda rules those out
also on the rear IRS arms , i think it would be nice to be able to change the rear camber , my DR's are worn more on the inside than outside
1 other thought on the front cradle , maybe lower the motor down some , i know i could use a little more room up top , and a lower center of gravity is a good thing too

If you go with a front steer the headers might have to be custom, all the headers are made for the rear stear. Might not be a problem though. I do agree that a rear sump would be much better.
There wont be alot more to post until the GTO gets into the shop that is getting back halved for the NHRA super stock class or what ever it is (I'm not a class racer so I'm not up on the classes)
That is the car that will get everything fitted on.
