Really Should Stop Modifying my Daily Driver into a Track Car

Its not 10 hours, bet its about half that if you drive fast.

Amazing build, How do you like the autopower cage? Do you still have plenty of room behind the driver seat to recline and street the car comfortably? Im planning on ordered the autopower even though I dont like how small the foot/plates are.

It has enough room for me to get comfortable, but not lay out.
It does NOT tuck tight to any roof or side panel.
The foot plates are too small in my opinion, and land in a very flimsy section of floor. Not the way I would build one from scratch, but I didn't build this from scratch.

Fusionworks: sold the mutant project. For better or worse, I realized I'd never get it finished and on track. Still waiting for the guy to finish the remaining money and pick it up though.

Question: isn't 10 degrees of caster quite a lot? What's the thoughts/purpose there? Coming from rwd, where 4-5 is as much as I ever see, im genuinely curious.

You are coming from a street car perspective. Most non European cars use less than 5 deg of caster. I am still trying to figure out the draw backs beyond stiffer steering, (which is nice at 130mph). From a race car stand point caster is free camber gain, better self stabilization, etc. You will see 12-20deg of caster in most race cars. For a strut car we have no camber gain and our braking and traction is severely limited by the amount of negative camber needed to keep the contact patch flat when you have no camber gain like a dual a-arm car. So you use positive caster so you gain more negative camber in a turn to help cut down on the amount of negative caster you have to run if you have next to no or worse positive camber gain. Running less negative camber means you have a flatter contact patch for braking.

Some pics of the race car parts when I pulled it off today to continue the development.


Yes the brake ducts are ghetto rigged for the moment. Part of the upgrade will be some attachment points for those like I have on my other arms. I am probably going to zinc plate the hardware and powder coat the arms. I kinda want to change the rear attachment point to something aluminum with a bigger bearing but these aren't necessarily a problem as I have them designed. I also want to add a threaded socket for the inner pivot point so camber adjustment is less of a pain in the ass.

I also picked up a rear beam to begin construction of my new up rear suspension. 2026 will be interesting for sure.
