5 x 98 on a 5 x 100

[Golf Houso]

Hey guys, I've developed an interest in some of the wheels on Alfas but was wondering whether it was possible to have a set of 5x98's on my VR6 with a 5x100 pattern on it?

I've seen people go from a 4x98 to a 4x100 with little or no effort but has anyone done or heard about if this is possible with a 5x98 wheels?

You'll need wobble bolts. They're basically wheel bolts that have movable tapered seats so that they can sit slightly off-set from the hole but still bolt on fine. I think the difference in PCD must be less than 2.5mm, so it'd be OK to use them to go for 5x98 --> 5x100. I don't know where you can get your hands on some in Australia but I know ECS has them.

Alternatively you can have the original holes slightly widened (professionally) to accomodate the 100mm PCD. More ghetto though.

Thanks for that Ray and Stu, I looked a bit further into it and found that these bolts are available for the Alfa's going to 5x100 although not for the VW's.

Although I think a redrill will be more suitable since the Alfa's run an M12 x 1.25 bolt at 5x98. I realise now that by simply increasing the diameter to suit a M14 x 1.5, that would only increase the PCD to 5 x99 as its not like a 4 stud car with bolts on opposite sides of eachother.

Whats exactly involved in widening the holes? Are they just squeezing the diameters out or?...

I've seen pics of wheels with the holes just redrilled out a little from their original positions. I'm no engineer but it does look unsafe.
