Want to give an update on keeping my track camber and toe settings the same on the street. It works fine!!
In late June after being without the car since its’ interesting weekend at RA in May for about a month, I have been breaking in a new engine. I knew I would not be tracking it again until my new shoulder joint I received on August 5th heals so I can work on it and drive it appropriately again early in 2022 at best. So all the street stuff was installed, and I decided to drive it easy and enjoy it.
I mounted my street brakes up, put on the street wheels and tires. I wanted to try this experiment, so I did not change any of my alignment settings front or back. The front tires are near new 325/30 soft Cup 2’s, the rears continue to be PS4S 345/30’s in their third season.
I am pleased to report and confirm a couple of things for everyone. The rear settings that approximate the near straight toe and for me near zero rear camber not only feel great on a track, this thing hangs great on the street. Our drag racing friends know these settings work great, well so do I now. I cannot imagine getting better traction overall with the lack of any hop due to my other rear mods. Tire wear? Non-existent unless I purposely file them down with too much throttle at the wrong time.
The fronts are where I am more than pleased to share info. I like reading discussions about camber settings and tire wear. Some of us know camber don’t do the tire wear, it is the toe setting that makes a tire wear difference. I discovered and minimized or eliminated the old outside shoulder wear nemesis in May. A set of brand new Cup 2’s up front showed NO shoulder wear after some aggressive track sessions!! That was both at RA and Brainerd. Previously I could bust a noticeable outside shoulder off in one session. What did I do different? AFTER adjusting the AAD fronts to maximum negative camber, I carefully adjusted the front toe. Before adjusting it, we discovered the change in camber blew it way out. I mean way out! That is why last year after driving it about 60 miles down a Oklahoma interstate we were absolutely blown away that the outside shoulder of the previous new Cup 2’s had no shoulders remaining early on Saturday morning BEFORE it even saw the track. All we could do then was note it and scratch our heads. I have the camber at around -2 degrees on each side up front, the toe is nearly straight on to just a hint of toe-in. A couple of you have talked with me and I have shown some pictures previously here. These racing fronts show NO excessive outside shoulder wear.
Better yet almost. After nearly 2000 street miles my other set of new Cup 2’s up front show NO inside OR inside shoulder wear! It steers so perfect straight it is an absolute pleasure to drive.
With some moderation of temps and humidity and with the engine okay to play now, all I am going to say is the previous unit may have been dog shit! Can’t wait to get this thing up to BIR and get some sector and lap times, because I believe I may have something different here.
