On both of my cars with the new front end, it felt like the front flex plates fatigued and needed replacement quicker than a set of springs would require. I think the reason was that the NFE has a huge amount of travel. Even after limiting the droop to .5mm the up travel was still some 10mm beyond where the chassis bottomed out. I suspected that running over dots, rubbing barriers, and wrecks would cause the arm to move up to it's full range placing a huge strain on the flex plate. This would lead to premature fatigue and delamination.
I made an up travel limiter and installed new flex plates. The car was consistent and turned some of the fastest laps of the race day without demonstrating any signs of flex plate fatigue.
What do you think Jason, can you engineer in an up-stop for guys like me who occasionally drive into things fast?
