I got same question as AMRAAM.

I got Racing Beat type II spoiler, similar to the 99spec
but a lil taller. I used a wolf Evolution 3 car cover.
But the pointy spoiler eventually ripped holes in the cover. The cover was good, but eventually got really
soft and started tearing and etc.. and It was only
water repellant at most and eventually not at all.

I am looking for a quality car cover sicne the car is
getig new kit and repaint.

So anyone out there got a Aftermarket spoiler/larger
than the R1's.. usign a Car cover?? if So what kind
are you using?? and if you guys got any SIZES to these
covers would be good.

As all you guys know, car covers leave like a car cover
mark/burn. Usually on the Mirror folded in or not, and
on the rear wing and usually the corners..
What do you use to get the marks off??
BTW I have a White FD, so that makes it more noticable.
you dark color FD's probably don't even know what
i am talking about..

I may try the Walmart covers, hell 40bucks.. why not.
Do you know what SIZE you guys use???

thanks
