We haven't been testing much lately, and it's time for an explanation. We'd been keeping this under the table until it was resolved, but thankfully we've got everything sorted out now.
Back in July when we bought our Tarmac 2s from Racecomp, we threw all of them on the dyno. Graphs are posted earlier in this build thread, and the more observant among you may have noticed we didn't post anything about the rears. We found an issue with one of the rears that was displaying some funny characteristics at high bump settings and high speeds.
We brought it to Racecomp's attention, who agreed something wasn't right. We decided to give them a chance to fix it before we publicly cried foul. The shocks came off the car, and went back to KW. We caught KW at a bad time, with various people on vacation, and it took a little bit of hassling on Racecomp's part before they finally got the right people to dyno the shocks and find the issue we were talking about. I guess it's a little out of the ordinary for them to have a customer dyno all the shocks as soon as they open the box.
They found an issue with improper preload set on one of the check valves, which caused a delay in the oil refilling at high speeds. If you're familiar with statistics and process control, you know that sometimes even the best companies have mistakes slip through the cracks. I certainly wouldn't let this turn me off from buying Racecomp shocks. We're still convinced they're one of the best deals out there for track-oriented suspensions.
In any case, the shocks are fixed now. We'll be back on track next weekend (the 29th) and fully expect to best our times since we're on a fresh set of RE71Rs. We'll also be testing out a Grimmspeed front strut bar, and installing our AP Brakes.
Summary
Dyno'd rear shocks, found an issue, Racecomp took care of us.
Lesson learned? It's always a good idea to test shocks on a dyno, and it's a great idea to buy them from Racecomp. They were nothing but helpful through the whole process, even if KW did drag their feet a little.
