It runs right at 10psi. I knew it was living on borrowed time at 450rwhp on a stock rotating assembly but I never thought an autocross would be what kills it.

Thanks I appreciate it, that wrap took forever, much respect to wrap installers. Unfortunately I broke the ring lands on 3 pistons which smashed their spark plugs causing us to ride home on 5 cylinders. So now I’m in the process of debating a forged rotating assembly or a coyote swap.. not what...

Hey man it was nice to meet you at the Triad event Sunday. Good luck at PITS. I was hoping to talk more after our run group but I acquired some engine problems during my 4th run, so after coasting off course my last run when I finally got it started we headed straight to the house.

I'm interested in what your plan is for the rear brakes. I've been debating the ATS brakes for a while now, I just haven't pulled the trigger due to possible wheel spoke clearance issues and not having a definite plan for the rear. I think my top option for the rears now is the Wilwood D154...

You have sparked my interest again... do you have any pictures you can dig up of this setup???

The current setup is simply an upper spherical axle bushing with a double adjustable upper control arm mounted in the stock location on the passenger side. Here are some pics of my car on a long sweeper at the last event. Keep in mind I'm still on stock struts/shocks too, only H&R race springs...

I didn't hit many events after the PM3L just due to other life events conflicting with autox schedule, but it was a significant improvement over the stock 4-link. The car handled better and was able to power out of the sweepers a lot better than before. My only real complaint about the PM3L is...

I guess I'll update this to not leave people wondering. By the time I got around to starting to cut off the torque boxes it had become so swampy miserable hot outside that I just decided to push this off until its cooler or I get AC in my garage/shop. Thankfully I started hacking the drivers...

I’ve seen on other forums people using Cadillac ATS Brembo 4piston calipers but I haven’t seen any of them actually race their cars. There’s also clearance issues with the caliper and wheel spokes so you’re limited on wheel options. I thought about trying it but not keen on running a 1/2” spacer...

Yea it’s a little overkill but I didn’t bother gauging up my suspension and measuring stress to run CAE so I just made everything thick to not worry about it. Correct, the rotation is controlled by the long mount running to where the weight was mounted.

Axle mount mocked up

Hopefully soon I’ll be able to update this, I was finally able to weld the rear mount together but haven’t had a chance to bolt it all on and throw the rear end back under the car for mock up. House projects have taken priority over the car for right now.

Thanks, I really just got a little carried away with the anti-rotation mount, I was going to have cutouts inside that maintained the same width as the top narrow part mainly just for the ascetics when all these people flock to look under my car lol, *sarcasm*

I looked into that but the panhard mount is pretty intrusive, the upper links would have to be significantly shorter. But given the OE uppers are ~8" shorter than the lowers it probably isn't that big of a deal, just more components.

So after checking clearances I have created a hybrid of Rev1 and 2 to push the mount behind the diff and utilize a 3" slot for adjustment and the central support a piece of DOM instead of bent bracketry for easiest fabrication. This leaves about an inch from the 3link mount to the panhard mount...
