I am looking for feedback on the 1/4 turn kit for the undertray. Positive or negative. Has anybody lost any pieces while driving? Any other negative feedback? Are they ok for track usage? Thanks for the info.
I've done 2-3 track days with my hangar111 kit. only the first event did one pop out, but the retaining washer held it, and easily retightened it back down. since then no issues at all. I hit the rumblestrips at track out and track in (where they exist).
The race shop took 30 minutes to re install my diffuser with the 1/4 kit.......
it takes me several minutes. it just requires a technique to do it right. Most effective yet was using a jack to prop the diffuser up and very easy from there.
find one you like, some people usually prefer one over another.
Personally I don't think it's worth it at all - but that's because I've modified so much under there that I can't really use mine anymore. When I added the side sills the 1/4 turns wouldn't even get close to reaching through everything. I finally removed the ones between the diffuser and shear panel too as it was just a pain mixing and matching them.
One of those things that seems great but IMHO isn't worth it. The install is a big PITA BTW...
