Long ball studs?
 

How long is the 'stud' bit on the x-long U3299 ball studs?

They claim to be the ones in the Cougar kit, but they don't seem very long.

The kit ones are only just long enough to get 2mm washer on them, I've no idea how Tom got 4mm of washers on them...

he didn't is the easy answer he used longer ones

Hmm, so what's the longer stud part number?

not sure but on the exploded view it lists u3299 as long for kit, but if you look at the parts list u3299 isn't in there?????

just looked at the cat sx rear super long ball studs and they are listed as u3299 im guessing these ar the longest ones im pretty sure the ones in my kit arent these at all,

I'm thinking the ones in the cougar kit aren't u3299, they seem shorter, hmm, well, I'll get a set of u3299 and see!

we have the u3299 on the rear of the cat and can get 4mm of spacing on there no worries

U3299 is the extra long ball stud and ball grippa.
U3498 is the extra long ball stud only.
The length of the 'stud' is 10mm.

That's great, thanks. The stud on the kit ones is 8mm.

So fingers crossed U3299 will be what I want anyway.
