BBS ra bolt size

Post

Back to the top
Hello… I am currently feeling that I am the luckiest person in the world right now !!! I have found 4 x BBS RA 15 6J in Black with perfect tyres !!!! €180 !!! Anyway what bolt size do I need. Radius or tapered?? My car is a 1989 MK1 GTI cabrio.. or will my bolts be correct?  I hate my P slots.  I have searched loads but I saw no definitive answer.

Lucky you!

If you already have alloy wheels on your car then the bolts should be the correct ones.

They should be a tapered seat as radius are usually for steel wheels only.

When you remove your existing wheel take one of the bolts and stick it through the hole in the wheel and measure the amount of thread that is sticking out. Then do the same with the new wheels to ensure approximately the same amount of thread is sticking out.

When you've put the bolt through the hole in the wheel pull firmly on the threaded side and make sure that when you try and wiggle it there is no noise and the bolt head is fitting snugly into the wheel.

Are your new wheels from a VW? I only ask as the size of the centre bore can be different as RA's were offered on Vauxhalls and Opels as well as some other makes and models.

Remember to torque the wheel nuts up (65lbft) and then check them after using the car for the first few times.

This might not be a bad time to invest in some wheel bolts anyway, once the wheels are on, as they can become fatigued over years of use.

Good luck

Thank you very much for that reply. they are VW. I will try as you have suggested. Now I understand the difference of the Tapered and radius bolts. Thank you.

If you want some totally reckless advice, I use whatever type in whatever wheel. 


P.S… don't actually listen to me.

Presumably when fitting 22" wheels from a Range Rover with a CB of 89 with no spigot rings and with an offset of -45.  O_o

Used to get loads of questions like that over on the polo forums. Young lads just starting trying to figure out why their wheels kept falling off  :lol:

'Yo blud, got sum ET0 9J wheels and my 145/60 tyres keep coming off when I go around a corner innit. Whats going on? I'm using quality Nankangs n evryting! "

Used to make me cry  :'(
