To fit radars you need a castle nut off ebay for a t25 that has a reduced inner edge
Spacers
I also had to grind down the swirls on my drum etc
Then you need to realise that the dustcaps won't fit
Ive just bought a set from sjh joinery via ebay but yet to open packet so will let you know
Prices ranged on eBay from £60 but I imagine they would be poor?
I've recently fitted a tmi to my sunroof and I wouldn't recommend trying it yourself,it's awkward and the fabric is pretty generic so needs lots of cutting and altering
