I want to replace the weatherstripping in my Z and was wondering if they are the same as the standard coupes. I'm guessing no, but I don't see anyone listing ZR1 specific weatherstripping. Does anyone know if they are the same?

Same as any Base C-4 they are not ZR-1 specific. GC

MRDZR1

Same as standard C4 coupe. My company designed and made those a few years back (we also made Ferrari's, Aston Martin and Porsche). I've actually found the dwgs last years while cleaning old files. We used ,and still do for service parts, a mix of sponge & dense EPDM and some with latex which is sh**T due to it's poor compression set but that's what GM wanted for cost saving matters.

So you know, if you by the cheap stuff you might have dimensional issues and much cheaper compound.

The company I work for Waterville TG Inc. supplies 95% of all Toyota's plants, Lexus, much Honda's, Ford and other JOEM's and now trying to get the next C7. I'm crossing my fingers because if we get it I will be the Program Manager for it.

So, since you have knowledge of the product, what's your choice for replacements? OEM or aftermarket?

Goldcylon

If its sealed in the package GM. Otherwise Wilcox

MRDZR1

Me? Of course OEM for weatherstrips.

I've seen some aftermarket roof side rails done in India on one of my friends C3 and it was 20mm too short because their compound doesn't meet the shrink test as per GM's engineering standard!!!

Not good to have a gap when to try to seal your car hey!

Ive also seen "Brand new" GM weatherstriping crack within a month of the installl. You cant beat the fitment I agree but it really POs me when I lay out $300 for a A piller genuine replacement only to have it crack and look as bad as the stuff you replaced in a very short period of time.

Age is the factor if its no longer sealed I would never buy it again. Its a gamble

MRDZR1

Your right, it need to be sealed, but if the molded detail cracked after a few months it's because the extrusion wasn't fresh cutted when they molded it or the molding compound batch was not to spec and that suck!

But plastic bags do slow down the aging process. BTW same with tires!
