I'm going to fit the Alu panels this Saturday. Next job is the rear wings, so how have you guys fixed them on??

I have searched and read about Sikaflex but don't fancy that - call me old fashioned but I prefer mechanical fixing.

So how did you do it??

drill and bolt with M8 and penny washers on mine. I couldnt by my "smaller" mates have sat on my arches with no disasters.

I probably could but im not wiling to try

Sikaflex plus 4 poprivets for peace of mind.

Pops and bolts - no PU - as they may have to come off.

Drilled and used self tapping bolts,the type they use to fit steel cladding.
I'd agree will hellfire re PU.
Cheers,
Bob

I'm gonna use 4-6 M8(ish) bolts and a strip of tadpole trim in between wings and side panels for a nice neat finish

We just used rivets all the way round, I think we used about 20 on each arch.

Used a washer on both the inside and outside of the rivet and tadpole beading sandwiched in the middle. Didn't have time to do both so we'll do the other one at the weekend.

the bolts used on cladding are called tech bolts. clever little things.

put threaded inserts in grp m5 bolts then penny washers and spring washers and tadpole beading about 7 per side quick too fit quick to remove.

As the man says they may have to come off to be replaced. as they stick out the tend to pick up a bump or too. The other half sat on one of mine and got a right bollocking for it! m6 with large washers spreads the load. tadpole beading to keep the muc under the guard.

9 x M6 bolts per side into nutserts with penny washers, tadpole beading ready to be fitted (going to paint first)

I used about eight M4 (maybe M6) stainless bolts on each side, with nylock nuts on the back where I can get at them, and rivnuts where I couldn't (i.e. behind the internal panelling).

I was working on the principle that I might want to take the wings off one day - and I did, about a month after fitting!

You can pick up the chassis rails and insert rivnuts for at least three of the fixings. Remainder in boot area with washers and nuts. Not visible then from inside car.

Anyone tried trim panel screws?

Basically a 5/8" long self-tapping screw with a plastic 'wall plug' fitted on it's end. As the screw is tightened the plug expands.

The plug has a 3/4" diameter head to stop it pulling through and the whole affair is short enough to fit into a chassis tube if necessary.

I was thinking of using these from inside the wheel arch into the Alu' and chassis where necessary - probably with a thin bead of sealer to stop any water from escaping.

Have a look at the Which Kit Indy build.
They used "captive nuts" rivetted to the GRP.

Jumpy,

I got my tadpole trim from MAC#1, £2/mtr

Someone once said it was worth using some sort of plastic/nylon clips. That way, if you hit something with the wing then with any luck it'd rip off without damaging the bodywork!

HTH,

James
