Looks great.

Did you guys add the chrome trim or is it a Cooper shell?


We added the chrome trim as this is not a Cooper shell

I was talking to an owner of an R1 powered Mini this summer and he too installed heavier clutch springs. Now the car is almost undriveable on the street since the clutch is now like a switch, either on or off. Playing with lever ratios on the linkage had only slightly improve the situation. Bike engine cars with essentially no flywheel mass take a bit of getting used to when starting from a standstill and the stronger springs just exacerbate the problem.

That's interesting since most people say the Barnett conversion makes the clutch feel more "car like" and not as much as an on/off switch. Either way, I agree the clutch will probably take some getting used to...

I'm loving your build, roadhouse. But I'm also hating it ... every time I read your posts, I end up going on Craigslist, looking for a Mini :BH:
As to the clutch, it is not a big deal. I installed the Barnett springs, but I don't think that they will significantly change the feel of your pedal. They are more needed for the clutch to deal with the extra weight of the car. The feel of the pedal can be improved by installing a spring that opposes the slave cylinder action. I've used a throttle return spring for a large diesel (heavy equipment etc.); it is long enough to mount the other end to the frame, and it is easily sourced from NAPA etc.
You will be slipping the clutch a little bit more than what one may be used to, but the clutch can take it.
