LotusTalk - The Lotus Cars Community - View Single Post - I hope the pace on track is better than pace of this project

Runoffs are over (and not very successful), so finally back to this project.

The factory track pack coilovers would not go low enough (due to reduced weight of the car), so I had to wrestle with changing springs, further complicated by the fact that the track pack Bilsteins use 1 7/8" coilovers. Many thanks to Doug Evans for pointers.

Also, finally updated the rear toe link, and this was my approach:

Also added the silly front splitter and went back to Rota wheels on front as the 949 Racing wheels interfered with the caliper unless spaced out 15 mm. Also got the ABS problem sorted out The car is now set up at 117 mm front, 122 mm rear ride height, 450 lb/in front, 500 lb/in rear springs, 1 mm toe in rear, 0 toe front, 2.5 deg negative camber front and 2.2 deg negative camber rear to start, on 8" front and 9" rear Goodyear cantilever slicks. With me on board and about 50% fuel the car weighs 1895 lbs, not as light as I would have liked, but the bits & pieces add up. It is all stock running gear, so no lightened rotors or uprights; may try some of that later when the major stuff is working as it should.

That tall center mirror is on purpose - the first time around I noticed that the mirror was right in my field of view looking toward the apex when turning right, so up it went. Details galore will eat you alive on these projects - this one is now into year 3!

I also updated the Hydra to the new 2.6 firmware and software and so there is more tuning to do, but thanks to Al Kibner for sending his cam map, as that should speed that complex tuning issue along. I still need to handle lots of little details, but the car runs & drives and has been on track for basic shakedown and I have reattached the parts that fell off and addressed the oil catch can issue, so inching forward.

Those who come to MSR come check it out most any time. I'll put you to work, though, so be wary!
