Only UOA planned for this car – looks good.
Winter Projects 2017
A number of projects lined up for the offseason: The largest of which was upgrading the evo’s brakes to Evo X Brembos, which use a much larger rotor (320mm to 350mm). The caliper, pistons, etc. remain largely the same but the braking is vastly improved by this swap. I went with the same DBA5000s &…
RaceFab Wet Sump Evo 8-9
Finally got the RaceFab wet sump installed. The Racefab wet sump is a heavily modified stock Evo oil pan. The wet sump comes with built in baffles, trap doors, and 2-2.5 extra quarts of capacity, making the total about 6-6.5 qts. It should help oil pressures in high-g right hand turns, which is more commonly…
UOA 5 02282018
Per below, some extra wear on this run. Oil ran for roughly a year or so, 63 autocross runs and 2,646 miles. Will be running Red Line 30wt race oil next.
STM Front Crash Beam Evo 8/9 Install
Having removed the front bumper in order to access the oil cooler, I decided it would be a good time to also swap in STM’s lightweight front crash beam. This was an easy 5.5lbs of savings directly off the very front of the car, while still providing decent protection up front. Since there are a…

Replacing the Reverse Switch – Evo 8/9
Noticed at the end of last year that the Evo’s reverse lights stopped coming on while I was in reverse. Found it unlikely that both bulbs went out at the same time, and they don’t have their own fuse – which meant that the reverse switch (switch on top of the transmission that tells the…
Maperformance Setrab Oil Cooler for Evo 8/9 Install
For one of the final pieces of the evo’s track prep, I decided it would be prudent to install an oil cooler, to keep the oil in it’s optimal temp range during these hot lapping sessions. After doing some research, I decided to go with a Setrab oil cooler, one of the top names in…
New Blog Address!
R56HS has now become QL Motorsport! Due to changes in priorities and cars, I have shifted the blog to become a more driver-focused site. I will still be driving the Mini for nearly half the autocross events, but have shifted the focus more to the Evo, prepping the car for autocross and track, and continuously…
Evo X GSR Wheels on Evo 9
Part 2 of the new wheels – OEM X GSR wheels to use as track wheels. I would be running the 265 width for SCCA autocross, but the limit for AWDs in street and most enthusiast classes for track were 255s. The X GSR wheels ended up being a good compromise that would be relatively…
