If you have the MK2 Phase 1 as I did, I would put money on it being 52mm which limits your options, AFAIK TA Technixx don't make them in 52mm variants, only the 58mm for non sports.
You have a few options,
you can do a 58mm hub swap etc so you're running phase 2 (16v) gear from the bottom of the coilover, that way you can run cheap coilovers, but have to spend the money of the hub swap etc (there is a guide on here somewhere, I'll find it if you're interested in this)
OR
You can save a bit more and get
VMaxx or
FK do them in the 52mm variant too, both similarly priced, I think FK get slightly better reviews on here than VMaxx.
First things first though, confirm your bolt spacing by getting under your car, either get it up on a jack, or turn your wheels full lock and poke your head underneath and take a ruler/vernier caliper to measure the bolt spacing at the bottom of the shock absorber. You won't miss them.
Remember it's measured by centre to centre of the holes, but top - top or bottom - bottom will measure the same.
If you want to go the FK route, please contact them to double check they're sending you the right bolt spacing set. I quickly found that link, not 100% sure if it's right.
I ended up just getting Apex lowering springs as circumstances changed, but I would have probably got the FK Highsports if I didn't have to sell the car.
