GrimmSpeed Reviews

Effin sweet company! 1) They do some pretty sweet PnP work, from what I can tell. 2) They are "local" for my area, which is still about 3 hours away haha (Iowa blows for getting work done). 3) They have the only maintenance free AOS system on the market (that i have found anyways), and I also got $100 off my AOS because of a group buy when it first came out. Me likey

GrimmSpeed is a pretty awesome shop based out of Minneapolis in MN. They do tons of port&polish work for Subies, on everything from turbos to intake and exhaust manifolds to throttle bodies. All of their porting work is excellent quality...and they also sell things such as a fancy air/oil separator, phenolic spacers, an EXCELLENT 3-port boost control solenoid for Subies, and exhaust pieces like up-pipes and wastegates, as well as various brackets.

Check them out, you won't be disappointed!

Very happy with my GrimmSpeed gold paint. Been on since May and zero flaking. A+

Awesome business!!!! The fastest shipping on any part I have had to buy for my subie. I will buy more from them in the very near future and looking forward to getting my manifolds, turbo, and intake manifold PnP and thermal coated.
