I had the MINI at Summit Point this past weekend on the extended Jefferson circuit and it ran great. I really like the new Bilsteins. Very predictable weight transfer, good grip, and nice ride-height. Currently riding about 40mm lower than stock in the back and 50mm lower than stock in the front. Could go another 10mm lower but don’t see the need currently. (Interestingly, the current height is 20mm lower than H&R Sport Springs on Konis.) The car isn’t slammed and the tires aren’t rubbing, but it is fairly low. I did have to not use the 5mm spacers I normally run on the street to avoid rubbing the rear arches (the wheels are 17 x7 with offset 37.)
Here’s a lap I filmed behind a student.
