Philip!
Well done, this is an absolute beaut of a build! How does it compare on track to the RS? Keen to see difference in lap times between the two.
Now I need more than one ride when I am next up in JHB :rollsmile:

M3
Rotinah, yes boet, Magoebaskloof knows that GT3 RS intimately! If at any time you drive through Magoebaskloof, stop at the picknick spot halfway down, get out and just close your eyes, listen carefully and you will hear the sound of the RS lingering between the trees
Guys, let me give you the specs of the M3, which I dubbed GT R. Not GTR, but GT R.
-body:
-Touring car wing, on duralumin brackets, mounted to the old boot hinge mounting points, must still be powder coated
-CSL replica carbon fibre (c/f) boot lid, fastened by Aerocatch clips, similar to those used for the bonnet
-roof panel c/f
-doors - light weight fibre glass (f/g) honeycomb composite doors, strappy type light weight door pull handles
-c/f GTR type bonnet with Aerocatch bonnet clips
-all tyre wells stripped out
-f/g front splitter, trimmed in c/f
-Interior:
-Touring car type roll cage to FIA spec in supaform steel tubing, roof was removed to install the roll cage, cage has a sub frame extending to the rear seat floor panel and through the floor for fastening of diff subframe to the cage for stiffening if the diff assembly and to prevent the floor from being torn apart due to increased stresses exerted onto the chassis and body, cage extends to engine bay to stiffen up front section of the car
-Interior stripped out, still a few plates an brackets to be removed, tunnel modified to shift driver's seat to the left, center to the steering wheel
-original dash retained but stripped out
-Momo steering wheel with quick release to enable easier entry and exit
-Cobra race seats
-OMP HANS-compatible 6-point driver's harnass, ATS Motorsport 4-point Passenger's seat harnass
-Short shift gear lever kit with exclusive BMW motorsport lever knob
-c/f driver floor panel and foot rest
-handbrake retained
-side and rear windows moulded from LEXAN, to original shape of the glass windows with sliding openers, with S-shaped ventilation tubes just above the mirrors
-Powertrain:
-Standard engine but fitted with new OEM big-end bearings and ARP-Racing conrod bolts, high flow induction kit, high flow twin tube exhaust with X-joint in secondary stage, single touring car outlet pipe , de-cat and only one silencer
-DASTEK Unichip conversion
-viscous fan removed, aircon system removed, only electric fan retained for cooling
-Braided high pressure p/steering hose
-Drive train:
-standard gearbox
-Suspension:
-H&R RSN race spec 3-way adj coil-over shocks, valved and sprung for the anticipated weight and type of track and all-tar race application
-adjustable camber-caster top mounting plates, rose joint mounting points
-rubber bushes replaced by purpose manufactured vesconite bushes where required, standard stabelisers
-Brake system:
Front, BMW 335i Sport Pack 370mm slotted and dimpled ventilated discs with 4-pot Sport Pack calipers, ducts in place of fog lights with duct tubing all the way to the purpose manufactured flanges mounted on hub assy, braided hoses, Endless pads, race spec fluid
Rear: std discs and calipers, braided hoses, std pads
Wheels:
Koya Racing A-Line rims, Yokohama tires 265/35/18 all round, front 5mm spaced and rear 20mm
Still to do:
-More neg camber (-5 to -7) at front
-Z4 steering rack for shorter steering rack ratio
-insulation of roof panel, Chrome grey tinting of windows to reduce cockpit heat
-single mass flywheel, sintered metal clutch plate and higher clamping force pressure plate
-recon VANOS and VANOS oil pump and -electronics
-light weight race battery
-when I am rich one day then I will replace the std wiring harnass with light weight purpose built harnass and Motech management system
-Aluminium kick plate for passenger
-diff to receive 3,91:1 ratio crown wheel and pinion
Total weigh saved: 345kg
Current weight with 1/4 tank fuel:1220kg
After new battery, fly wheel and further diet, 1180kg anticipated
Respray in original Phoenix Yellow
That's about it!!!
Any questions???

Gavsadler, I will take you for a spin on trak at a BMW Gauteng Car Club track day, that is when we can take public for a spin. Otherwise the navigator's seat belongs to a special friend, my ex-rally navigator Cobus Böhmer from Pta.
Rotinaj, a seriously hot N54 might beat the RS in a straight line, but never in the bends, unless it is a fully stripped out full race spec car

It was fabricated by a manufacturer in Pta area, who supplies ADF.
I had a look at quite a few c/f skinned doors as well f/g doors, these guys fabricates the best looking doors of all. Cost per door is about R3000
I would like to mention that I learned this past week that ADF was actually a previous business in which Freddie Pretorius traded in motorsport.
His current business is actually known as Fast Development, all the old clients just still refer to ADF.
Anyhow, I dropped of the M3 today to have the last lot of mods and fine tuning done.
It gives one such a great feeling to see your own racing car parked between some of the best and most notorius racing cars in SA, that has been built by probably one of the most talented race car technicians, or should I rather say, experts!!

Mr Smit,
Your car looks great, plus all the mods are complimenting the whole build.
I must say, I like the pic of the underside of your rear spoiler...reminds me of when the craze of fastening a mirror to your school shoes to look up the girls dresses...but that view is a whole lot better than the upskirt shots..:rollsmile:
The weight of your car, with the power under the hood must surely make one smile when you tramp the loud pedal!!!

Jô, my wife almost smacked me against the head just for reading your post!!!
I never thought of the mirror trick, I only had academics and cars on the brain. But yes, I must say that I sat behind the M3 and admired the rear end more than once, but it was a mechanical beauty admiration, not a feminine type one, as my M3 is a he of course, not a she....
Now that makes me wonder about you ....
The M3 is not thát sort of car okay!!!:crazylaugh:
Just joking boet.
The power to weight ratio is up from a standard 210bhp/ton to 320bhp/ton!!! Yes, when I press the loud pedal it really gets moving forward very fast
