BMW E30 Rear Diffuser

[blackmist27]

Does anyone know if there is anyone in the US that makes a decent rear diffuser for E30s? There is a company in Russia that makes one but not sure i feel good about sending my money overseas and praying for the parts to arrive... but if anyone has any experience with these guys let me know:

I like this one...but again, a bit risky i think.

Are you doing this purely for looks?
Or is it a track driven car that you are looking for better aerodynamics and more downforce with?

To make a proper rear diffuser you need to cut the spare tire well out. Not just bolt on a flat piece of metal for $150.

^^ Removing any turbulent surface (the areas around the wheel well) and making it laminar helps, but yea it's not the best way to do it. Plus it looks mad tyte jdm

most people have custom aero fabbed for their needs since track, suspension, and power all change the downforce requirements.

Yeah... i was thinking more of a ratio of 60% looks, 40% function. guess there is no good option.

It's fine, but it's a better idea to consult a fab shop, spend a little more, and get something that really helps your needs-- rather than something that may help a little, or may hurt a lot.

When I was exporting CNC components from Russia it was all titanium....and so cheap :)
