Last weekend was the first full race weekend since the redone Dedion was put in. Before the event I had added a heat shield to the ABS pump+accumulator, and reset the front alignment to 2 mm toe-in. It was very hot, about 100F on Saturday, but probably about 15F cooler Sunday. Roxanne ran great all weekend, only needing gas
I ran the Nittos NT01 all weekend, must be the 3rd or 4th weekend on those tires, and they are holding up fine. I did swap the two rear tires since the left rear takes a beating in turn 8, 9 (high speed and full throttle more or less) and turn 2 at Willow Springs. On saturday (in 100F) coolant was running 220F, engine oil 230F, and transmission oil 230F.
I was going to include some plots from the datalogging of Gs, speeds, etc, but my laptop where the data is crapped out. Anyway, Roxanne pulls 1.3Gs consistently through both left and right turns (tires: Nitto NT01 205/40-17).
Based on tire temps it looks like it may be optimal to slightly further reduce the camber at the rear and possibly also at the front. Though, ok for now (=too much trouble, particular the rear).
I do have one problem. Roxanne eats rear wheel bearings like crazy
Both rear wheel bearings were new before this weekend, and both need replacement again...
Not sure what is causing this - could be the spacers (25 mm) increasing the load... Guess I could make a 3rd dedion with slightly less camber, 25 mm increased track per side, and then use a 25 mm spacer on each half-shaft.
Unfortunately, I forgot to put in the video camera, but I think I will be able to get some pictures from the weekend.
Next race is October at Buttonwillow...
