So, I am about to embark on the first winter job on my MK Indy which is replacing the standard arches with wider ones.
I have the arches now, but I wanted to see if anyone had any tips for getting the best fit?
As I didn't build the car I don't have any experience in fitting rear arches, but my plan is to remove the old arch, offer up the new arch
and hold in position with G clamps and try to mark the new arch hole positions to match the current arch mounting positions?
Once fitted and I'm happy, I'll remove and transfer the lights and stone guards etc.
Thanks!!!
Use Tadpole trim, trap the tail in between arch and body. But make some V shaped cuts in the tail so it will fit round the curve with out getting
kinked.
Make sure arches are fitted on correct sides, I've left arches seen that have been fitted on the right side, which looks a bit odd.
Fit them with nyloc nuts/bolts and penny washers to spread the load. Think I used 5 or 6 on each arch.
When i fitted mine i measured from the center of the wheel to the arch lip and tried to get the measurement as even as possible, nothing looks worse than a massive gap all round IMHO but make sure you have enough gap for full suspension travel
Spend an extra tenner and use stainless fittings.
Good advice above, tadpole trip with V cuts in the tail so it follows the curve of the arches, stainless nut/bolt/penny washer fixings so you can
remove the arches in the future and ensure you get them the right way around.
Take your time as well to make sure you get a matching fit and finish across both sides!
Stick camping Matt on inside of arch stops stones cracking glass fiber.. Used old fashioned impact adhesive..
In a similar vein to the above I sprayed the inside of my rear arches with a thick rubberised coating that also contained embedded GRP strands.
I'll try to find the name of it.
I attached my rear arches with plastic radiator fixing kits. So when I hit something on the track they break off and don't damage the
bodywork.
The rubber trim from Woollies I put between them but the fitment on the westfield was really good so I didn't use it for that.
Hi all...
Sorry to hijack post, but this is the newest thread more or less on topic...
My rear arches do not have a mounting flange, I am thinking to make some 1.5 mm thick stainless steel angle brackets and use a couple of rivets to
the skin and one allenhead screw with washer to attach the arch to the brackets.
Planning on 5 per side.
Does anyone on here has attached arches without flanges to bodywork?
Pics any?
5 Brackets per side enough? Too few? Too many?
Thanks in advance.
If they are glass fibre I would have a look at fitting some flanges using glass fibre matting and resin , should be easy enough to make a neat, strong job.
