G'day, I'm half way through a 45mm coil over conversion to my 120Y struts.

I got a set of larger stub axle 120Y struts, a otomoto 45mm coil over kit, Kev Rowley S13 brake caliper brackets and S13 brakes ready to go once I machine the hub down to slide the S13 brakes over.

My problem is now working out what strut insert will be best.

I've read the Mk1 Golf insert will fit, I went to Heasmans and they didn't have the Mk1 Golf inserts in stock but they had Porsche 944 ones which are the same 1.5inch (38.1mm) diameter.

They didn't really come close to fitting in, they said they would have to machine down the body of the insert and maybe get the strut honed out.

Then i'd need to cut the strut down 100mm and get the end of the strut tube re-threaded, either on the inside or the outside of the tube.

But anyway a good insert in 38.1mm isn't easy to come by in Australia, and I'm not real sure how much I should shorten the strut by for good ride height, 100mm seems a bit much.

Has anyone gone through this process in Australia, and what inserts did you use?

I've searched on here but the information isn't in as much detail as I'd like.

I've gone so far now with the 45mm struts i don't want to ditch the idea for 50.8mm ones, then my Kev Rowley brake upgrade won't work.

Also has anyone used series 1-2 Rx-7 inserts? They seem to be the same 38.1mm body but are a bit longer than the Golf's at around 352mm which sounds ideal. Plus I could get a KYB or Pedders pretty easy.

Not sure is Bilstien or Koni are worth it for a 95% street driven 1200 coupe with a L18 in it, or with the heavier motor should I spend the extra and order some Bilstien Golf inserts from the states?

Any advice would be awesome, cheers
