Here's my first outing in STU - the car is damned good, the driver is rusty as an old farm implement left out all winter in the back forty...




Cheers,

Charlie

Pace

Man, that boxster was six seconds faster over a roughly one minute course. That's HUGE!. Will be interesting to see how MINIs fare in STU in other local events

Gollum is nowhere near the STU rules limit - a Quaife and some good coil-overs are what's missing, 'cause 9" rims and at least 245 tires seem hard to do. . The e-Diff and the Sport Suspension springs with Bilstein B8 shocks are good. Ride height is stock.

I am not a fast enough driver to reach the car's' limits in optimum fashion. If I can get Brian Levesque to share it with me, then I will know. The car is better than I am for sure.

So be aware of the nature of the data....

Cheers,

Charlie

Nice job. I took mine out for my first time this last weekend as well, ended up 35 out of 60 Raw and 27th PAX. Definitely have a lot of room for improvement and learning on this car. I think I could of won my class (DS) of 3 if I wouldn't have picked up a cone on my fastest runs each time (we did a mini pro style with 2 courses and 3 runs each course). The class winner was 19 Raw and 10th PAX. I feel like the mini is oddly classed in STU and DS, stuck in classes with a bunch of RWD or AWD cars.

What pressures are you running? I was running 37-38 up front (chalk marks would scrub off to the edge) and ~40 in the rear. Car wouldnt rotate much for me, but it didnt push really bad into the corners either. I started at 35 in the front and 37 in the rear and kept going up, I felt like this was a good pressure as anything above this and the car would start to understeer and below this I was getting too much sidewall flex. I'm on 205/55/16s btw. I really need a rear sway bar.

36 front, 40 rear

that is a lot of pressure for re71, are you camber limited? On my stx car I ran -2.8 up front and was able to get the pressure down to low 30's the grip was much better.

I switched to SMF and have not looked at STU, out here there is no way to be competitive in stu it would be a 3+ second gap it's really sad they put the turbo mini's there

Point taken, and perhaps less is more. The car has -2.1 out front, and the 8" rims support the 225s very nicely, so it's worth exploring.

Thanks,

Charlie

Maybe it is due to my tire height? I am on 205/55/16s. I chalk my tires before every run and I tried 35. I ended up scuffing below the the triangle on the sidewalls. I didn't see a reason to go below that psi as I assumed I would see more roll/sidewall damage. I am camber limited right now in the front to stock (basically 0) as I dont think there are crash bolts and I am in DS. I am running ~ -2 in the rear which I believe is stock and slight toe out in the front. I wanted more by my arm was seized up and we couldn't get it to budge. Once I replace that I will probably dial in a little more toe out.

Ahh I figured you were setup for stx, at least -2.5 up front. I can't afford to autocross on 0 front camber
