Solid part for my AUDI RS4 B9.5. The carbon quality is good and the weave is consistent. Shipping took a few extra days but CT Carbon were responsive when I emailed them. Would buy from them again.
Matt Collins –
Bought this part for my AUDI RS4 B9.5 after seeing it recommended on a forum and I’m not disappointed. Quality is exceptional — real pre-preg carbon, not a cheap overlay. Will be ordering more parts.
Owen Mitchell –
Top quality part. Bought it for my AUDI RS4 B9.5 and couldn’t be happier. The carbon matches the quality you’d see on professional race builds. Shipping was fast and packaging was solid.
Noah Evans –
Very impressed with the quality of this part. Fits my AUDI RS4 B9.5 like a glove — even the mounting holes lined up perfectly. Packed really well in foam and arrived with no damage. Free shipping sealed the deal.
Tom Barker –
Love this part for my AUDI RS4 B9.5. The gloss finish is mirror-quality and the carbon weave is consistent all the way to the edges. Took about 30 minutes to fit with basic tools. Would absolutely order again.
Connor Phillips –
Proper OEM-quality part for the AUDI RS4 B9.5. No drilling, no modification, bolted straight on. Looks incredible and completely transforms the car. CT Carbon really know their stuff.
Kevin Hughes –
Exactly what I needed for my AUDI RS4 B9.5 build. The part is flawless — perfect carbon weave, no bubbles, no orange peel in the lacquer. You can tell it has been made properly. 10/10.
Ethan Clarke –
It is a good part for the AUDI RS4 B9.5 but not perfect. The fitment on one side is slightly off and there is a tiny bubble in the lacquer on one corner. CT Carbon offered to help when I raised it, which was good of them.
Scott Reynolds –
Nice part for the AUDI RS4 B9.5. Fitment is about 95% — one edge sits very slightly proud but you would only notice up close. Carbon finish is great. Deducting one star for that small fitment issue.
