OK smart people, please help me out here...

I have received my new Carrera GT rear arches, and have no idea how to install them in a good way

I know I have to cut the existing arches and weld them together to give more clearance - that i have no problem with, it is the installation of the new glass arches I am not sure about. As you can see in the picture, they have a leading edge, now I will assume to install these and make them look good, I will have to create a sunken edge in the existing body work on the car to install these so that there is not an edge that I will have to try and hide - or am I wrong about that?

Any guidance and advice (treat me like the idiot I am at the moment) would be very appreciated

you should cut the old arches for the wheels to fit...weld them if you like...i didnt...instead i filled the gap with a special compound used for car bodies called mastic.
The arches should be riveted on...you dont need to sunk anything...you just add filler and sand everything so it looks nice.

top tip: use lots of rivets.
good luck.

sorry no pictures from the install...you can only see the final result if you look around the board. The hardest thing is to position them and align them...then rivet them in position.
When i installed mine i had this tutorial of how to position them but i dont have it anymore...do a search...maby it will pop up...tough the search almost never worked for me.

No problem, I will see what I manage to do.
Yes, I have found the search function here not so helpful

I just would prefer not to do the job twice

OK, did a first test fit this afternoon

What do you think, does this look like the correct alignment

I am not 100% sure about the left to right alignment. I know that according to the crease it is a bit to low. I can not find a good straight on side picture of a 924 with the GT arches to see how the arch aligns in relationship to the actual wheel - should there be a bigger gap at the rear than the front, or should the wheel be central in the arch?
Also should the rear tail end of the arch sit flush with the rear bumper?

quick tip... welding the inner lip is the best way but their are other options.... if your going to br putting bigger wheels on at some stage ide strongly suggest getting them FIRST before fitting the flare, they will give you a better idea of how far forward or back to put the flare.... see fezzas car below

http://924board.org/viewtopic.php?t=25868&start=0&sid=d53dc265f62d61a8798ba9be3018bade

note the final product will be directly proportional to the time you put into moulding the flare into the body...note fezzas smooth contour into the body.

If it has a rear inner lip make sure it is cut to fit the wheel..fezzas wheels rubbed the rear inner lip untill it was trimmed off...

Rivets only, eh? I'm doing Canadian impressions today.
I would think some type of the epoxy glue + rivets, no? (That was my Frenchman impression.)

another tip: dont take the wheels(specialy not the tires) as basis for your measurement...i'd say always use the body of the car for measurement basis as the rear arms can sometimes be bended or missaligned.

Defenetly get the wheels you want first and put them on.

Thank you all. The word document that Scorpio linked to is just what I was looking for. The body is the last i will do on this car after all the suspension has been sorted out and the 944 upgrades are done. Then I will get the new wheels etc and as a last thing do the body work.

i just like to have all the things I need up front - makes me feel more in control. I hate to start a job only to find i am missing something half-way threw

Hi. As above I would definately get the wider wheels before fitting the kit. Once the arches are on they are on! Heres a link to the installation I did last year:

Billson... any luck with the wheels?.. was thinking of using ET20 mustang rims, and machining a small disc out of the centre cap so that the hubs could poke through a little without spacers

Line up the creases with the body creases. I bolted and dual epoxied the flares on.

You will have to cut the wheel wells about 3 inches in the center and slope to the bottom. Weld the inners to the body.

Fill in the body after with fg to seal small gaps.

Before you do anything lower the rear of the car and get it level. I think everyone should do this before anything. It will handle better.

These flares are thin and subject to crackes if someone leans on them. I layed in about three sheets of FG on the inside of the to stiffen the arch.
