AC Schnitzer Type 1 Rennsport (OZ Racing) - Build Thread

[yalden]

18" AC Schnitzer Type 1 Rennsport
(2pc by OZ Racing)

I thought I'd share my build thread that I've put together over the last year on a UK based forum (wheel whores).

I'll edit this thread as and when the final touches on the wheels come about.

After owning the car for approximately 4 months, the long search for the right set of wheels finally came to an end when I managed to bag myself the above set up for just £250, largely due to a misspelling within the advert title.

As can be seen, the dishes are all tarnished, some more than others. Likewise there are various degrees of kerb rash.

ADDITIONS/MODIFICATIONS:-

07/07/08 - AC Schnitzer hubcentric spiggot rings (purchased from Rossiters)

Because the wheels were originally purchased privately for an E36 M3, the fronts are meant to be fitted with 7mm hubcentric spacers to prevent the wheel from fouling the brake caliper.

As I don't have this problem I do not require the spacer, however to ensure a hubcentric fitment, I called Rossiters and ordered a pair of hubcentric spigot rings @ £15.

14/10/08 - Gold plated split rim bolts

Upon good recommendations, I made contact with Claus @ Felgen-Garage (http://www.felgen-man.de/english/indexenglish.html) to discuss my options with the wheels.

Whilst deciding which future set up I would go ahead with, I placed a quick order on a 165 shiney bits...

I couldn't help but play around with the set up, if only to take a few more photos; bare in mind the centres of my wheels bolt from the front, so the bolts won't sit up against the dish as per the below photos, instead they'll sit within the recess of the centre.

07/08/09 - Tools & Stickers

After looking into the simplistics of splitting my wheels I came to realise that the bolts used by Oz Racing to secure the wheels are custom 10-spline, as opposed to regular 12-spline.

A little digging soon unveiled that two custom sockets (8mm/10mm) would set me back £100, thankfully fellow member Rob-G-Clarkson had already forked out for such tools and was now loaning them out for a small fee of £10... ideal! Needless to say, they were on the door mat within a couple days.

On the same day as the sockets arrived, I also received my original OZ Racing lip decals from Germany, to be located opposite the tyre valves on the outer edge of the dish - the lips would've had these fitted prior to polishing through the clearcoat.

Whilst splitting the rims, I thought it'd only be right to have a quick trial fit on the rear...

15/08/09 - Making a little back

I decided the original barrels were worthless; tarnished, kerbed and corroded beyond reasonable repair. As a result I thought best to weigh them in, bagging myself a swift £21 - which has now be deducted from the build total :lol:

28/08/09 - Centre Piece Refurb

Albeit that the centres of my wheels weren't in awful condition, they were showing some light marks/scratches/chips and general discolouring. Originally I was going to get my bodyshop to respray them, but I had concerns over the durability of the finish and the overall coverage within each split rim bolt-recess.

I did a little bit of digging, which was later reinforced by a few recommendations and decided to send the centres via courier to the Leeds based shop of The Wheel Specialists (http://www.thewheelspecialist.co.uk).

I opted for the Hi-Power silver powdercoated finish; £186.28 (inc. courier) lighter, but no regrets!

http://i15.photobucket.com/albums/a388/yalden/Z3/th_centres1.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/centres1.jpg) http://i15.photobucket.com/albums/a388/yalden/Z3/th_centres2.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/centres2.jpg)

http://i15.photobucket.com/albums/a388/yalden/Z3/th_centres4.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/centres4.jpg) http://i15.photobucket.com/albums/a388/yalden/Z3/th_centres5.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/centres5.jpg)

They were also asked to smooth the centre caps however I'm not 100% satisfied with the overall finish (there appears to be a slight imprint of bubblewrap texture embedded into the paint - assuming they wrapped them before the paint had fullly cured). Rather than send them back I'll probably just get my local shop to repaint them.

28/08/09 - Rebuild materials

Hopeful to rebuild the wheels tonight, I thought best to purchase a few of the essentials from my local Kevin Cooper outlet, totalling £13.28!

28/08/09 - It's Schnitzer Time

60 weeks since purchasing, they've finally been treated to the well deserved make-over

I got the relevant parts together and began by using a mixture of saturated aliphatic and alicyclic C7 to C12 hydrocarbons with a maximum content of 25% of C7 to C12 alkyl aromatic hydrocarbons (e.g. white spirit) to ensure a clean/degreased surface for the sealant to take to).

A narrow bead of sealant was laid around the perimeter of the barrel, once complete, the wheel sections were laid into place and secured by quarterly bolts.

Once secure, the remaining bolts were inserted, dabbed a single component thixotropic chemical called dimethacrylate ester (e.g. Loctite 243 / Threadlock) and torqued to 22.7 ft/lbs.

A final bead of sealant was applied to the outer edge, where the lip and barrel meet. Although my efforts might not have been as 'neat' as some, I'm confident there'll be no air-leaks on my watch.

http://i15.photobucket.com/albums/a388/yalden/Z3/th_rebuiltfinal12.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/rebuiltfinal12.jpg) http://i15.photobucket.com/albums/a388/yalden/Z3/th_rebuiltfinal13.jpg (http://i15.photobucket.com/albums/a388/yalden/Z3/rebuiltfinal13.jpg)

The fronts remain 2-piece, so none of the sticky stuff necessary. Ideal - a quick and easy bolt on affair (with the aforementioned threadlock/torque settings).

29/08/09 - OZ Racing Decals

Something I wasn't happy doing whilst building the wheels was fitting the OZ Racing sticker; I had no reference material so was worried I'd place them incorrectly.

I've tried to ensure that the wheels are built as originally intended, the minor detail is to ensure that the valve is located central between two spokes, with the OZ Racing sticker directly opposite. Needless to say, this is now done.

Just valves, centre caps and tyres to go...

http://home.filternet.nl/~kjv/new_button.jpg 28/09/09 - Making a little back (no. 2)

The front tyres that came on the wheels at the time of purchase still had plenty of life left in them, with about 5mm of tread. One eBay listing later and they made back £67 - which has now be deducted from the build total!
