How Heat Resistant Is Carbon Fibre?

[PM-R33]

Hey guys,

Just wondering, how heat resistant is carbon fibre? Obviously the actual fibre itself is very heat resistant but what about the clear resin coating? Say a rear diffuser is touching on an exhaust is that ok, or will it melt into the coating? I'd rather not have to cut it for the sake of half an inch, but if it is going to melt the shit out of it ill cut it Also with regards to cutting it, will it fray the ends? I've drilled into carbon before and it was perfectly fine, but never actually cut the stuff. Any tips?

Thanks

it really depends on the quality of the resin, or the clear coat on the top,

carbon fibre is fine with the heat but the clear coating resin and craze or peel off, it wont melt, so id say leave it to let it craze, in the end if it makes it look bad cut around it

pics of r33 gtst rear diffuser?

[PM-R33]

It's half installed, ill post pics once it is fully on. It needed a bit of modifying to get it to sit the way i wanted. The way they are made they sit fairly low and my car being low to begin with wasn't a good option lol. So i had to mount it as tight to the body as i could which in turn turned out looking a lot better

interested in photos to, should look good, especially on a white 33

[PM-R33]

Yeah looks really good. Finishes off the car nicely with all the other carbon exterior bits.

nice one, what needed to be modified to make it fit exactly? im assuming that ur using the psi parts r33 gtr diffuser?

look forward seeing the pics

Yep the PSI parts one Gorgeous piece of gear.

Im taking all the pics of fitting for them (up to about 100 at the moment) and writing an install thing so they can use it as a guide for others. There is two main ways to fit it. First way is probably easier utilising all three pieces together but leaves to many gaps and doesn't make the diffuser sit nicely IMO (most likely since it is made for a GTR). The second way is the one i have done which tries to bring it as tight to the body as possbile. Needs more modifying but looks better i believe. I will go through the install in more depth in a new thread once it is completely fitted and post up all the pics.

Here's a couple just to give you a rough idea.

Here's the diffuser:

This is it when we were trying to get it to sit the way i wanted, still being supported by oil bottes (i ended up getting it sitting more flush with the body afterwards once the front bracket was modified):

This was the last photo from the other night once it was supporting itself with 4 brackets, the car is still on stands however. Sorry about the night pics, tomorrow after work ill try to finish off the other brackets i want to make up. Ill then take proper pics of the car out in the open and post them up.

It is a 3 piece diffuser and is made to sit with the side pieces supporting the main piece. Personally i didn't like it this way so made the main piece sit up tight to the body and will try and modify and cut the other two pieces to sit them on the outside to increase its length, instead of increasing its height.

Well turns out it aint damaging it in anyway with slightly touching on the exhaust

any more pics of this mate? about to buy 1 from psi parts to go on my gtr when i get it.

whats the build quality like and is it easy to install?

[PM-R33]

Installation was a bit fidly because i mounted it a bit differently since it is made for a GTR and it sits fairly low the way they mount it. Quality is superb and havn't had one drama with it since installation.

I wrote up a DIY for PSI parts to send out with the kits with plenty of photos of the install.
