Sorry but BMR parts look like a high school metal shop project, I can make nicer stuff in my garage. No way I'd put BMR anything on my car.

sorry but I really don't care. Here is the fix, take it or leave it.

uh, oh. hope this thread doesn't turn into an ls1tech.com style bmr vs. ___ thread lol. FWIW I am happy with their 4th gen products.

But this looks like a nice solution. Heck, even the 350z Hotchkis bar had to be re-designed with a flange to keep the bushings from slipping.

Anyone have thoughts on tire pressures for my setup? I normally run a ND miata in STR and my SS 1LE is my time trials car so it's set up for SCCA S2. It's stock but with 19x11 square with 305 goodyear SC3 all around. Tomorrow for giggles I was going to autocross it in CAM-C but wondering where tire pressure should be. On track it seems happiest in the 32-34 range I think but obviously on track the pressure moves much more so I'm just guessing (I start at 28 and by the end of the session it's 38). Was thinking I'd start at 32 square and go from there but was curious if anyone had thoughts.

Regardless I'm looking forward to hitting literally every cone on my passenger side haha.

My best results, and imo best feel, with SC3 on OE wheels was to have the front at 32-33psi and rear at 28-29psi. I would bleed off to those pressures after a couple runs then check each run afterwards. In the summer (85*+ ambient temp) on 305/19 Rivals I would run 33psi front and 31 rear.

First event on the Falkens last weekend. 1st Place PAX at my local event, the 660's sure do seem to drive different from the stones. I found they really don't like blended inputs as much, I seem to really have to wait before I can get on the loud pedal

Ditto, 2.5 seasons on my hotchkiss bar & bushings and no issues so far.

First event, have a little center rib tire wear, falken 315/30 on 11” wide, went 32psi hot, camber is at -2.7, I know I need to go up more, autocross with 16 runs. Anybody else have this odd inner tire wear? I don’t want to lower pressure too much and roll over the edges, but I’m guessing lower pressure and more camber would balance out. Temps where only about 4 degrees higher in the middle. Thoughts?

That course looks amazing!

Thanks! I never ended up going lower than 30 in the rear but I probably should have. I ended at 32/30 which was better than 32/32. Car was quite loose, but I think that was mostly because I just have too much front grip for autocross. Fun though.

I can't see very clearly in the pictures but your center ribs look great for falkens. They like to do this weird peeling from the edge thing on the center rib. It's kind of a meme now among the SSC guys who have to run the falkens. But anyway I wouldn't be concerned unless there's something there not visible in the pics.

The re71s of similar design does the same thing. Eventually it may look like the re71s with the center rib having the outer edge and rib being more worn

Good to know, the wear is good for 16 runs so far. Just the peeling had me worried, I ran the first rivals and had delimitation on the edges, was hoping this wasn’t the same thing.

I saw similar effect on RE71r (275 width). It evened out after several events.

[DaveC113]

My 305/30/19 RE71s look similar, though to a lesser extent. Seems like they may like more camber but the outer edges are not excessively worn so IDK.

Also, I managed to beat a gt350 with a really good driver on Sunday by about .06s for a 2nd place in CAM-C. I had a run 1 full second faster but hit one cone, would have got me top a 10 PAX, maybe next time... ended up 17th this time, which I'm very happy with.
