    At the end of the day the money for a fully built box will be Worth it all day long when youve got a super car power car for sub 20k and the fun that car will bring you will be endless fun specially when you’ve got the hpa controller

    Yeah mate it’ll be really interesting to see how the car reacts haldex wise standard and when a HPA Controller is plugged up. I am secretly excited for the slight wining I’ll get when the semi dog gears are engaged..... just hope it’ll be as quiet as possible when on the motorway doing 70mph haha

    Further update on the gearbox, it’s now fully assembled and the case is ready to be fitted and put into the car. Really stoked, Martin has done an awesome job on this..... for anyone looking into gearbox upgrades he is the man for the job.

    Not going to lie, can’t wait to get into it, run it in and see what it’ll do on that G30-770. A couple friends of mine are wanting to do a road trip to Germany in March with there (Road/Track) cars.

    With the steel forks, 4th input shaft modification, 3-6 monster performance gear set I think Martin said it’s pretty solid to around 1000bhp / 800+ ft lbs. I won’t be anywhere near that so it should take anything and everything I throw at it.

    A little project I’ve been working on over Christmas period. I managed to find a genuine AP racing CP5570 big brake kit, which consists of -

    330x28mm 2 Piece brake discs
    6 Pot AP Racing Calipers
    DS2500 pads
    Stainless Steel brake lines

    This is a “Factory” Big brake kit for our cars, designed to be used on track and road, so the calipers come with an additional dust seal. To buy this new you would be looking at £2900. I managed to get it really cheap, however the chap I bought them off didn’t mention how badly they were corroded. “Good working condition” they were not! Pistons were seized up, clearly hadn’t had any attention given in there ownership. So rather than return them I decided to refurbish them.

    This is how they looked before the refurb.

    This is what they look like now.

    I stripped the entire set apart, removed the bells from the old discs and sent them to a local company to strip back and get hard anodised again. There is a little bit of pitted in the bells but I’m sure they’ll be fine.

    I replaced the discs with Reyland J Hook 330x28mm and used Genuine AP Racing 25mm bell/disc bolts torqued up to 15nm.

    I had bought a little ultrasonic cleaning machine and put literally everything in it to be deep cleaned, which worked fairly well.
    [​IMG]
    Worth there weight in gold, simply fill with water, I used a glass container, put the bolts, nuts, adaptors, the lot into the container and filled with a degreaser and after a rust remover. Came up almost like brand new.

    I had trouble removing the old bleed screws and some of the pad guide bolts........
    [​IMG]
    At this point I decided to contact someone to have the calipers professional stripped and rebuilt with genuine seals, etc.

    I contacted a company called (pro-caliper) based in London. Thomas was a god send, even he was struggling with the pistons in the calipers but came through and put them back together nicely, 2 day turn around!! He usually specialises in Brembo calipers, but he clearly knew what he was doing.

    After I got them back I cleaned them up one more time and sanded them down, I repainted them with E-Tech XHT black and E-Tech XHT clear coat. Admittedly I did get the misses to paint the yellow recessed AP Racing logo, I don’t have the patients for it nor a steady hand.

    Really really pleased with how they turned out.... I’m going to use these this year on a few track days and see how they are, eventually I’ll look to change them with the AP Racing CP9660 brake set up that’s commonly used on BTCC cars, a few members on here use them [mention]desertstorm [/mention] [mention]Prawn [/mention]

    They've come up really nicely, particularly given the state they were in before. Good stuff!

    Gearbox and brakes look really good. Not sure I would like to put 800Lb/ft through it, still has stock first and second gears but I am sure it will stand up to pretty much anything you are likely to throw at it. DS2500 pads are not the best on track as I am sure you are aware, See how they go on the road and maybe try something better for the track.

    Thanks dude, I would have liked them to be powdercoated ideally. But because of the AP Racing recessed logo, no one wanted to touch them?! They turned out a lot better than I thought they would.

    Thanks Karl, yeah I’m guessing if you went full 1-6 monster performance gear set then it’s a safer bet, I think monster performance do drag racing primarily so lots of very hard launches. I don’t intend to launch the car everywhere, even with most things covered in my build, things are still liable to break for sure.

    One of the reasons why I bought these AP racing calipers was for the ease of swapping out the pads, I’ve run DS2500 on the road for a few years and have been pretty good, but your quite right..... so I could easily swap out the DS2500’s for something more suitable for the track.

    Any suggestions what pads you’ve found to be good for track? I have eyed up a set of Pagid RS29’s but I think they are similar to the DS2500. Something that bites hard but doesn’t have masses of fallout

    RS29 is on a different level to DS2500. That is what I was running in mt RS3 4 pot calipers with the V6 334X32mm discs and they were very good. Pad life not quite as good but stopping power was excellent.

    Interesting you say that mate, did you notice them squealing at all at low speeds? Apparently there really good at slowing you down but not stopping if you catch my drift. It shouldn’t matter too much on the track, just if I left them in for a drive home or something after a track day.

    Anyone had any experience with DS1.11’s or DSUNO’s for track and road? Reason why I ask, apparently if you use Ferodo DS range when you swapping the pads out for road use or track you don’t have to re-bed them in.

    For anyone wondering what my Gas&Gears (02M FEK) gearbox ratios are...... also my anticipated speeds at 8200rpm redline this of course depends on how the G30-770 reacts, if there is room to move the redline out more or less. This is also based on a wheel and tyre size of 245/40/18

    1st 3.818 (42 mph)
    2nd 2.105 (76 mph)
    3rd 1.533 (104 mph)
    4th 1.176 (136 mph)
    Final drive ratio 3.938

    5th 1.176 (169 mph)
    6th 1.000 (199 mph)
    Final drive ratio 3.150

    MPH between gear changes
    1-2 (34 mph)
    2-3 (28 mph)
    3-4 (32 mph)
    4-5 (33 mph)
    5-6 (30 mph)

    If compared to a normal S3 02M gearbox these ratios are only slightly shorter in the 3-6 monster performance gears. However they are longer with the diesel gearbox final drive ratios.

    Standard S3 02M gearbox ratios at 8200rpm

    1st 3.417 (44 mph)
    2nd 2.105 (71 mph)
    3rd 1.429 (105 mph)
    4th 1.088 (137 mph)
    Final drive ratio 4.200

    5th 1.097 (173 mph)
    6th 0.912 (208 mph)
    Final drive ratio 3.316

    MPH between gear changes
    1-2 (27 mph)
    2-3 (34 mph)
    3-4 (32 mph)
    4-5 (36 mph)
    5-6 (35 mph)

    If I were to use the S3 02M gearbox final drive ratios at 8200rpm it would be like this.

    1st 3.417 (44 mph)
    2nd 2.105 (71 mph)
    3rd 1.533 (97 mph)
    4th 1.176 (127 mph)
    Final drive ratio 4.200

    5th 1.176 (161 mph)
    6th 1.000 (189 mph)
    Final drive ratio 3.316

    MPH between gear changes
    1-2 (27 mph)
    2-3 (26 mph)
    3-4 (30 mph)
    4-5 (34 mph)
    5-6 (28 mph)

    With these final drive ratios you’ll be changing gear like a mad man which was one of the main reasons why I choose to use the taller final drives from the diesel gearbox. Also when doing 70 mph on the motorway I’ll be cruising at 2850rpm instead of 3050rpm with the original S3 final drive ratios.

    You’ll notice that the 1st gear I’ve used from the diesel gearbox is actually shorter than the original S3 gearbox. However the 2nd gear is taller, this will eliminate having to change into 3rd gear to reach 60 mph. This should make a huge difference to the 0 - 60 seconds and on the track as it’ll mean less gear changes hopefully.

    After much research and watching [mention]Prawn [/mention] review I’ve decided to get a set of CBAutos (Paul) rear 300mm bells and caliper adaptors for the back of my car. Took a little while for them to get to me. All put together on some Wilwood UL32 non handed 298x20.57mm discs. Would have liked some nice J hooks to match the fronts, only seem to be AP Racing that do them but they are around £130 each! Where as the Wilwoods were £57 for the pair from demon tweaks.

    Really impressed with the quality. Look forward to getting them on the car when I get it back from Badger5

    I’m looking at options for change the rear caliper as well, but I’ll see how these fair on the track in March all being well.
