SE autocross and suspension thread.

Yes, I looked at that possibility too. I think the spot weld flange above the top link needs some trimming, but then one could clamp on a machined bracket with a new hole above and forward from the existing upper pivot. Clamping to the flat where the existing hole is would provide enough stability.

I already have two holes in my bar, so bracket stability should be fine. It's tough stuff to drill. I did manage to squish the stock bar flat while it was on the car with a hydraulic crimp tool. But the somewhat thicker 918 bar needed beating with a sledgehammer.

No setup tips, but I did enter my first 'real' autocross last weekend. Rainy conditions, but I was surprised how well the Hankook Ventus (OE tires) did in the wet. I heard that the better AX tires never got hot enough that day. I ran in Sport mode with full metal nannies since I'm still learning the ropes. That's it until March for autocross at PIR. I will need new tires for next season.

Anyways I was 2nd in Novice class on Saturday and 1st in "Not for points" class on Sunday, ahead of several Miatas, GR86etc, and Corvettes. My clean laps were 6-7 seconds off the raw winners' times over a mid-50's second course. My navigation skills need a lot of work :0

I rode in a Miata that podiumed on Saturday and a Golf R that won on Sunday - bonkers! I also rode in a CHEVY VOLT of all things that was 2 sec faster than I was on a 60 second lap. He normally runs a 350Z(?) but not in the rain. To be fair, his driving was very smooth and his lines were impeccable for that vehicle. The Cybertruck was a bull in a China closet but it looked like he was having fun.

You'll be surprised how much better the car brakes and handles with proper 200tw tires.

The collar screw are the axle bolts that the manual says should only be used once. You are also supposed to change bolts holding the bearings to the hub carrier. My local Mini dealer has good prices on parts online. If I collect, no shipping This is still a rather pricey way to get an extra 0.5° of camber. It is legal for all SCCA solo classes, though.

I ran at NC autocross state championships weekend before last. Saturday, Vitour front, Yokohama rear. Got my *** kicked. Wasn't really warm enough for the Vitours. Sunday my heat started wet, I put my ECS02s on. I kicked ***, until the course dried out, then slipped back, but not too badly. The ECS02 have much higher rolling resistance than the stock kooks, so I don't really want use them as dailies. Some people use them as dual duty tyres. The stock 'kooks will get shredded if you autocross in the dry. Since they are great daily tyres, I'd recommend you pick up a set of wheels for autocross. Smaller diameter helps with acceleration and also lowers the car a little. But if you go to a lower load rating tyre, you'll need to up pressure. So stay away from 18s. 15s are a major hassle with the rear brakes. 16 or 17 are the easy choice. There isn't a big selection of wheels in 5x112.
I've found a '919 JCW rear stabilizer bar to be optimum for both daily use and autocross, with added holes. I used various crude methods to mash bars flat before welding up a 10lb tool with a pair of m16 bolts that I apply an impact wrench to. Changing the rear bar should take a competent mechanic 3-4 hours if they read my guide. Somewhere near the beginning of this thread. The battery does not need to be removed or disconnected, the rear subframe needs to pulled back and down, after disconnecting arms.
I run nannies as off as they will go. That does require some sanity to be applied to the situation when things get a little too sideways... It's been educational, as well as entertaining for spectators. I am way, way better at controlling it now. If I'm not going sideways, I'm not winning... Fortunately one of the venues I go to has more runoff than other sites have total space, so I can really let rip there.
If you see an EVX M3P, make friends and get a ride along. They are bonkers fast.
