That may be the case, but when a customer tells them EXACTLY what they are going to do with the car, the power levels, the current or expected 60 fts, and what transmission they are using...They should get it right the first time. Not put street junk in it and charge them for the "race" quality parts they asked for. Hell they even went so far as to use the brand of gears they were explicitly told NOT to use. Then when I have it taken apart by their own employees and they tell me that it was the poor choice of parts that cause the rear end to grenade, on top of the fact that they used a crush washer in a "race" application that obviously called for a solid spacer. One would think that telling them "I will be leaving the line off a 2-step at 72-7500 RPM with a 5 speed manual trans" would be enough information to keep them from doing something so stupid. Oh, and after hearing "you're lucky the rearend didn't lockup and throw you into the wall" about a hundred times, yeah I was a little pissed.
Here's and example of how well their crap held up after about 25 passes. Per DTS this was caused by excessive back-lash due to launching the car and the rear-end being built with a crush washer instead of a spacer. This excessive lash caused the ring-gear and spool to shift rearword in the housing resulting in axle tubes that were bent forward by nearly an inch and a bunch of broken teeth.
The boys on Groesbeck are completely lacking the necessary racing background to be working on anything other than a stocker, bottom line.
The IONIA guys however definately know their shit, and they build your stuff so you can thrash on it again and again.
