It’s has been a while since I’ve posted in this thread. I took the car apart this past winter for some upgrades and still do not have it back together (getting close though).
My goal was to upgrade the 45 year old GM front spindles to some stronger spindles with higher load rated bearings.
I ended up buying a complete package from Ron Sutton Race Technology. Ron designed new custom front spindles, and a brake package to work with my stock front sub-frame and Global West Tubular A-arms. The geometry of the spindle is optimized to improve handling over the stock spindles, and the steering arms are adjustable so I can fine tune the steering ratio (quicker for autocross... slower for road course). The new brake package will increase my total braking torque from 2352 to 3404 (major improvement... can't wait to try them out!).
Some of these pictures are posted in the chassis and suspension section under "front suspension & steering geometry" but I wanted to update this thread to.
Here is some pictures of the new parts:
Spec 37 rotor with custom billet hub.
Wilwood large 6 piston calipers
Howe upper & lower ball joints. Low friction coating... bigger diameter. Stock upper ball joint shown on lower left.
Billet aluminum steering arm
The steering arm has an insert that you can swap out to change the location of the tie rod mount. This allows fine tuning of the steering ratio. This pic shows the caliper mounted to the spindle.
Custom optimized spindles
Large diameter spindle
Massive Timken tapered cylindrical roller bearing
Now I have all the parts in my possession... I'm back from vacation and I’m working to get the car back together.
Upper ball joint mounted
I plan to install the rest of the parts this week. I'll post pics as I go, and provide more info on the adjustable length steering arms.
Look forward to trying out the new parts very soon. Kudos to Ron!
