I'm not sure they really work that well. I once had an animated discussion with the leader of a Le Man's team (Panoz) in the pits at 2am. They had a front engined car and a Carbon prop to "protect the driver when it let's go". I suggested that it might be better to use a metal one which wouldn't let go too often. This wasn't a welcome suggestion as it was against their design philosophy (and they lost the prop on a regular basis throughout the season). The bottom line is that designing a Carbon prop isn't too easy as the material doesn't react well to out of plane stresses. It was a few years ago (Noel Edmond's "team" year) so the technology might be better now. Steve

I was suffering from this too. It tends to go just after a long run; presumably heat soak causes the adhesive to weaken. Had a blat Tuesday and an hour after garaging, the front plate was on the floor. Gave up with tape and have just stuck it back with Sikaflex 221. This seems to work well but removal later might be a pain Steve

I'd try to check the stud thread for distortion before relying on new nuts. Access might be difficult but if you can get close enough with an eyeglass, look for the thread profile being 'skewed' towards the stud end. Steve

Bolt strength isn't probably an issue here as the bolts clamp the rack to the chassis. The forces from the road to the chassis are reacted by the friction in the clamps so as long as the bolt can deliver the required torque, they should be fine. Brittle materials wouldn't be a good idea here. Steve

3mm is the smallest I could find but it makes the bonnet stand proud a bit at the front. After sticking down I used a sharp knife to taper the first few inches down. It's still a bit proud but less so. Steve

I've just filled up and the gasket is outside the boot on mine. Steve

I concur with Jonathan. Even if you can get a good welded repair, the loads that caused the original crack are still there, so some form of doubler across the cracked area should be used to reduce the stress. Welding ally in situ can be a problem as the heat can induce weakness around the weld making future cracks more likely. Removal for welding allows the part to be heat treated after the welding is completed. It also makes reinforcement easier. Steve
