UrS4 2.2T Avant project

Ok, what brand? Cheapest I could find was >20euros/kit.

These came with some other bits, so practically for free.

Starded to work the coils, removed the springplates and cutted the steering arms loose. Will weld the arms back on in a lower position on the strut. Resized the hubs to fit the new brake discs. Tried also to fit the front calipers, and they need a special bracket to fit the UFO strut and 360mm disc. Only problem seems to be finding a M12x1.5x25mm fine pitch countersunk socket bolt to clear the lower fitting point to the strut. Ideal adapter thickness would be 13mm, had only 12 and 15mm plate so I did 1mm stainless washers to use between the caliper and adapter.

Looking good. I see why you need those bolts now

Alex, the bold seems to be quite rare, but they can be found from here for example: http://www.nssocketscrews.com/stocks...prodCat/METRIC Did send them a enquiry, will see what they cost... Other plan is to make the hole smaller on the bracket, tap it and fit a bolt from the other side.

I am sure you have a fastener supplier who can get them in Finland? I would speak to my guy here, but he is uber slow unless the order is worth £££

Ok, thanks Alex. I did ask my "dealer" that usually source me bolts but they didn't have that kind of things.

How do you use the lower bore in the adapter?
I also tried this way at my HP2 strut.
Wasn't enough room. I will check for a picture. There was something limiting the room... Hmm.

Check the axial clearance of the caliper to the discs.
I had to rework my calipers that there is enough room.
I used ZR/ZL 18 brake pads.
The 17" shall be smaller and better but never tried personally.

The idea was to use bolts like these:



But seems they are very hard to find, so maybe I'll use a normal pitch bolt from the disc side. Have to cut new adapters with a smaller hole, and of course tap a thread in it.

TJ:FYI
just found the old photo from my friend's car with 18ZR Cayenne Calipers.
350mm disc,stock mount.

Pop, that must be HP2 hubs? It's possible to assemble these 18Z calipers directly on the UFO hubs with 350mm discs(needs only shimms), but it leaves the caliper in a different angle, more upper position than in your pic. And I wan't to use the 360mm disc without any modifications.

I forget you have UFO struts right Thomas?and yes that's HP2's.my caliper also sits way upper(09.30 o'clock)position.fabricated the bracket is a good plan since you just finished everything in one single time but i guess you're not going to replace the rotor discs at the end of every tracks season Personally i like your brackets designed.you're really great on fabricated everything.i hope i could have you next door lol.Be ready for the solid bushings mate.i got quids in my account though.

Time will show how these drilled Zimmermann rotors will hold on track, may they crack? They are quite thick and massive size, so I have good hopes on them.

The caliper just fit straight on hp2 's without any modifications?

I know, but i don't think the struts on S4 B5 look the same as the urs6 struts.
