[quote][i]Originally posted by Graham88[/i] [quote][i]Originally posted by SVM 286[/i] Just wondering Graham, did you ever consider incorporating a fire wall, when you were having all the prep and paint and cage work done in the back of the car? :) [/quote] I did consider it yeah as I saw an E36 M3 with one installed with the cage going through which I liked. And then putting thin felt and giving it the Clubsport effect instead of painting it. In the end I just went with painting, simply because it was easier :lol: [quote][i]Originally posted by Wrighty[/i] fair play for ripping an m3 to bits as far as you have :lol: [/quote] In terms of some people I know with M3's that have bought them purely for track cars, mine seems very normal still :lol: [quote][i]Originally posted by Haimsey[/i] Just read your thread from start to finish, great read. Certainly been no expense spared on it :lol: Looks fantastic from the outside especially! Good job. [/quote] Cheers mate. Nice to see someone appreciating the efforts and time put into it :thumbs: ________________________ Just realised I haven't updated it since I came back from Ring. As you may remember I was having clutch/gearbox woes. Gave me no end of problems at Spa as it was obviously getting hot which seemed to be making the crunchy synchros worse. In the end around 4pm it was refusing to select 3rd so I called it a day, bit gutted but I had to bare in mind a 400 mile journey home the next day, or rather everyone else told me to stop going out and slamming it into gear as I'd decided the box had had it so I didn't care anymore! Once it cooled down the next morning it was ok again (still crunchy) but it was selecting gear at least as that would have been a pain driving home. So back in the UK I looked into rebuild costs for my gearbox as new ones on eBay were £700+ for a manual box, £400 for an SMG one. Everyone basically said they weren't economical to repair, with parts costs being more than buying a new box, and that's if you can get the parts. So I set to buying a new box, and after a bit of research it turned out the SMG used the same gearbox as the manual except it was controlled by a pump and actuator instead of a gearstick obviously. So I bought one and we set changing it over. There was actually 2 differences once we had both gearboxes next to each other. Because of the way the SMG is controlled and with displaying the gear on the speedo, it doesn't have a reverse light switch like the manual. Manual: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-3.jpg[/IMG] SMG: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-2.jpg[/IMG] So we tapped a thread out for that, but the tap design means it wouldn't thread right into the box like manual, so as it wouldn't sit in enough it wasn't 'switching' like it should as we were testing it with a buzz meter,this was proper confusing as me and a couple of mates were trying to figure out when it should be buzzing and when it shouldn't :lol: In the SMG picture you can see a dowel and basically a spring sits in this which presses the switch in the you put it into reverse and puts the reverse lights on which looks like this: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-8.jpg[/IMG] The manual dowel was shorter, but as the switch wasn't sitting in the box as tight as it should, we had to use the longer one, but this meant there was loads of thread showing and the switch couldn't be tightened so it could loosen over time and then not work anymore. And basically with lots of trial and error this is how it ended up: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-4.jpg[/IMG] And great success the reverse lights worked when we mocked it up and there were high fives all round. I'm not even joking! Now we hit our second issue, the gear selector rod was loose as arseholes on the SMG box, and basically this is because the actuator holds it in position whereas on a manual it literally goes straight up to the gearstick, so this means the gearstick would have been really sloppy. This is due to a simple spring setup in the manual box to hold the selector rod in position. This is machined into the box so I was now cursing as this also had detent springs machined in aswell, basically alot more work than I thought this was going to be as I was told the SMG box was a straight fit. The SMG gearset is exactly the same as SMG is just a sequential manual gearbox so I looked into getting the gearset swapped over to my manual box, and again it was coming back as uneconomical to do, I was close to burning my car out at this point! With the manual box being fucked anyway me and my mate decided to just take it apart and have a look, so we drained the oil out and took the bell housing off. After looking at the gearset and thinking fuck that I looked at the bellhousing and the spring setup I needed was in the bell housing holding the end of the selector rod in position :! :thumbs: Manual: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-5.jpg[/IMG] SMG: [IMG]http://i18.photobucket.com/albums/b112/GrahamVFR/BMW%20M3/Gearbox/null-6.jpg[/IMG] So we just swapped the bell housing from manual to the SMG box and great success, the selector rod was held in position by the spring, and I was happy again :D I also swapped the flywheel from the lightened one back to the Dual Mass, as this was the last thing left in the puzzle of what could be causing the clutch fault. Put it all back in and drove it, all seemed good, noticed no difference in the flywheels either.... My mate rang me and said there was a Novice evening at Brands for BMW's, can't have done more than 3 trackdays for £49.....so we booked on. Was brilliant weather, I ragged my car for 2 hours, it didn't go wrong, the gearbox feels like brand new (SMG can't crunch gears so synchros felt NICE!) and the clutch was returning how it should be. So after 9 months of problems and god knows how much money spent on the clutch system it seems like the lightened flywheel was the problem after all....not happy about that so I'll be getting my money back on that! Also got a 55.2 second lap round Brands so chuffed with the cars performance now! Little hack with my mate in his Dad's CSL. http://www.youtube.com/watch?v=BiznskOoyPc I should mention I did that with rear brake pads on the metal :o :lol: luckily I found someone who deals in AP pads near Brands Hatch and cheap, so got some Pagid RS29's the next day and put them in. Then I attended BHP Show at Lydden Hill on Bank Holiday Monday and did a private session with a few mates just to show the car off more than anything if I'm honest to show it gets used and not just a poser car. The video is shite as I must have knocked my Go Pro mount and my car wasn't really any good around the track which was slippery as fuck so struggling for traction out the bends, http://www.youtube.com/watch?v=OVVhxpsMnq0 but it was a good crack and good to test the box out again before booking a full days trackday again.
