It's funny you should suggest them. These are the tops I've been leaning towards

As it turns out, Burtons are $60 cheaper! Thanks for the advice.

And yes I agree, $450 a pair for stage 2 Kmacs is a bit steep. I will be getting my swaybar from them though
 

Haydn,
checkout GRP4 Fab. site they have the same strut top for 58 euro. I have these on my struts

Great stuff, good to see it progressing. 
 
You could also get a spacer kit for the M16's and then you can fitted vented rotors.
 
You can get them from SMCKA for $50.00.
 
Cheers,

Hi Peter.
Cheaper again! Thanks
Matt
yep seen the spacer kits around. Not really worth it for my car. And I'm making an effort to keep all mods legal. Cheers

Sorry to hijack, but as we are on the topic
 
For those pondering, the MP179 listed by burtons is manufactured by GRP4. The prices from burtons and GRP4 direct are exactly the same (once VAT has been removed from the burton web price). Make sure your get the right collar set with these tops aswell (purchased seperately)!! You will get 4 pieces (2 sets of collars). One set is placed through the central bearing from the underside and the other one is placed through the bearing from the top.
 
Be warned, these will raise the height of the front end on a mk2 by 25mm! I have witnessed this myself on my own car. So plan for that - otherwise an excellent bit of gear!

Thanks cheese. I had questions about these and you've answered them all

No worries! Glad to help!

Bearing and seal kit all fitted and packed, minus split pins :)  Thanks to Jamie @ Component Restorations for his help and advice.
Next job is assembling and fitting the struts to determine threaded sleeve position.
 
 

Assembled and fitted drivers side today. It's in the car, I just need some time to measure up.

looking good mate.
