Had a 350z rear spoiler of them, that fitted over factory boot lip spoiler. Had a bit of a twist to it, so either end would not fit flush at the same time against the boot lid. Price was reasonable though unusable. Managed to sell it on.
EPR racing was advertising one but when ordered they told me the previous customer told them fitment was crap, so they refunded me. I found one through another seller and the fitments great. Ive checked they have none listed.
Vossen look sweet. Wonder if anybody has gone deep concave on the rear, and on the front too. Would they supply this or would you have to purchase 2 sets obtain the look.
Spray well with WD40. If this fails a little heat with a blow torch usually does the trick. Standard decat usually produces CEL light, so a spacer can be put in to eliviate sensor issue. Got my spacers from Zmanalex.
Get a quality 4 channel amp. You might want to upgrade/replace the wiring loom the same time. I just removed my old bose amp from the boot, taped up the old loom and ran new cables. It all depends on the sound and the power output you want to achieve. Keep us posted.
