This product sketches me out for several reasons:
1. It's supposed to fit all these models "E30 E36 E38 E39 E46 E49 E90"
2. It's adjustable.
3. Their company banner features a Mitsubishi mirage with lambo doors and 20"s (hence mirage power)
4. Their slogan is "driving like without the speed limited"
If I were you I would just get strut tower braces.
The E30 is what all actual driving enthusiasts are after. It's an unpretentious machine, quietly capable of spectacular feats of handling. It's light, simple design is rugged enough to run against $400k rally cars, but on the street it' communicative chassis delights even the most disinterested driver. It really is one of the world's ultimate driving machines
