Noticed this after a run yesterday. The small section of the underfloor that extends I to the rear wheel arch section is cracked. Can't say I remember any knocks or noises that may have caused it but it's there alright. I'm guessing it can be fixed but it ain't gonna be cheap?

I can only think it may have been a big bit of grit I ran over that got flung down onto the part causing it to shatter. May be worth looking at some kind of shield to fit over it once it's repaired so it doesn't happen again

One of the vendors sells a protector that clips onto that area to protect it. It seemed like a good idea but they were out of stock, so I bought some heavy duty edge protection to cover it. This stuff: https://smile.amazon.com/gp/product/B00NL3YN7O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. I probably looks more finished than factory, and keeps that area covered. You might be able to put a bit of glue appropriate for SMC to ensure it doesn't spread and then put on some protection like this stuff or the other one and avoid the need to have non-factory paint blended in.

Edit: Here's the one sold by a vendor, Centerline: https://centerlinealfa.com/catalog/seal-4c-rear-wheel

The link should take you to the size that I went with, Part Number: 100B3X1/16-25 | Size: 25 feet | Style: 9/16 inch leg; 1/16 inch edge fit. You could probably go with the size for 1/8" edges too since this has the small lip, but with the aluminum inner structure you can kind of form it around the lip and it's a nice tight fit.

Actually - I have about 24' of this stuff left. I think it took 8" sections on each side. If anyone would like some, PM me your address and I'll mail you two 8" sections.

Could have been something thrown up....but did anyone try to jack the car up....or run it onto some sort of a lift that could have snagged there?

Strange that this should be happening, I'll be checking my 4C as soon as I get it out of the garage, (I've been away for 4 weeks and now have severe 4C withdrawal symptons), it may be worth adding some sort of protection so I'll be looking into that. BTW, the 4C panels are not fibreglass but SMC (sheet moulded composite) which contains fibreglass, so I'm not sure if standard fibreglass repairs would fix it.

Definitely sorry to see this. The 4C seems to not take kindly to road debris, Things that would just bounce off any other car seem to be causing some serious damage to the lightweight composite panels than the 4C is made out of. Hopefully you can find something that will be sufficient for a fix, as I am sure that the replacement parts are very costly!

That sucks. I'm not sure where on the car this is. How about another picture that shows the relationship.

The rocker and rear fender are fiberglass and should be repairable, easily. A Corvette repair shop would be a good place to start.

A lot of cars were damaged like that during delivery. The hold-down straps inside the enclosed trucks go over the wheels and then down to the load floor. But if the attachment point was not directly next to the wheel the strap would be at an angle and touch the bodywork there and cause damage.

Well, i have checked mine today and apart from the chipping (not broken/cracked yet) on the bottom part...i have it slightly cracked on the upper part (on both sides of the car) near the screw that attaches the two panels...ffs









We can't avoid road debris or gravel on publics roads or dirty sides of tracks...so, since it isn't going to be a Garage Queen, i think i'll go with JWA suggestion as well to protect a little the lower part, at least.

Feeling kind of pissed though...
