ok, heres what I did. ive had my set up for 7 years although I haven't used it as much as id like the last few years.
ive had to change the steering gaitors a few times as the lower wishbone bolts are constantly rubbing on them.
as I was looking under the bus again this year I was thinking I cant just keep changing them and needed a long term solution. when I got into it I found another problem....
the allen bolt used by red9 has a large nyloc nut which is the problem. there just isn't the clearance for it. I looked into finding a dome headed bolt or something similar but nothing is available in the size or the strength needed
the wishbone mount measures about 85mm across but the bolt supplied isn't long enough to cover this distance on the shaft, you don't want moving parts running on the threaded section but that's whats happening here.
I spoke to a couple of nut n bolt specialist I know and found the right size bolt. had to order an entire box from the Netherlands, not cheap but not much choice! now if you don't know bolts have different strength ratings. you can buy a cheapo bolt which will be maximum of 8.8, you can also get much stronger spec 10.9 and 12.9. I couldn't find or they don't make the size I needed in 12.9 so im using 10.9. T25 use 10.9 and they are heavier and vw did all the research so im confidant with the 10.9 spec. the red9 kit is very much like the T25 set up anyway.
have a look at the site re bolt strength

this is the wishbone mount
and these are the bolts. the top one is the one in the kit. the bottom one is the new one I bought. you can clearly see the difference in shaft length... no sniggering now :lol:
I took a flap wheel and a file to the new bolt just to take any sharpness off the edges. I didn't go too mad just rounded it off
here you can see the rounded bolt, a stock new one and the one supplied in the kit. the nyloc is quite large
I fitted the new bolt the opposite way round so the head end is by the steering gaitor rather than the threaded end. the good thing about this is the old one slid out as the new one slid in. meaning all the washers stay in place
so I went from this
to this
there is more clearance that it looks like in the last pic. the bolt head isn't touching the gaitor anymore and I do have the option to knock a little more off the top if needed. hopefully that will solve this little problem.
I used the nyloc and washer from the kit on the other end and fitted a slim washer under the bolt head
im probably going to change all the bolts on the wishbone mounts as they must all be running on the threaded section rather than the shaft of the allen bolts.
one thing I must make clear is you cant just put any old bolt in. if you do what ive done then please check the strength rating of the bolt used. any bolt not up to the job will simply shear in half. so keep it 10.9 or above and for god sake don't use stainless steel. might look pretty but its not strong enough.
if you want to change them as you have had the same problem as me I do have a big old box of them now so pm me if you need them.
finally im viewing this as rectification rather than modification. its a pity it wasn't sorted in the beginning but im not going to open that can o worms again.
hope you all understand my ramblings
cheers
