KatoKid Posted November 26, 2017 Author Share Posted November 26, 2017 So my motivation to complete the car was to have it ready for the Vic BBQ which was today. The car was ready but the weather wasn't and I've vowed that it will be a dry weather only car and not even washed with water....I've got too much tied up in this and want it to last for another 40+ years! I took some photos with my wheels of choice a few weeks ago, the day was pretty dull so they aren't great photos. The wheels are XXR 513 16 x 8 +0 and will probably polarize people....I like Wat's for sure but wanted something a bit different.

KatoKid Posted November 26, 2017 Author Share Posted November 26, 2017 Thanks guys, I'm happy with the look. What tyres did you end up opting for? Ended up with Bridgestone Potenza RE003. They are on special with a buy 4 get one free deal so was pretty attractive. I originally got 225/50/16's as all the research I did said that these would fit but no way.......my car sits very low with the MCA coil overs and the RE003's have very square shoulders so I had interference on the lip (rolled) of the rear guards and the back edge of the front valance panel so I had to go down in size which actually looks better as it looked over tyred with the 225's....looked like a Matchbox car!

KatoKid Posted December 10, 2017 Author Share Posted December 10, 2017 (edited) I've racked up nearly 800 km now in the car and I'm over the moon with how good this thing is. The only real bug I've had is a quite pronounced vibration that came in bang on 100 kmh. I spent some time on the road and hoist trying to diagnose the issue and was pretty confident it was the tail-shaft and specifically at the diff end not the transmission end. I double checked alignment with lasers both directions and all was good so I took it back to Jeff at Knox driveshafts to have him check the balance. It was out just a little but not enough he said to be causing any noticeable vibration, he did suggest checking the run-out on the shaft insitu as you can have a balanced shaft but excessive run-out will still cause vibrations. My shaft consists of the standard BMW guibo rubber donut at the transmission end and CV at the diff end with an adapter to the R200 pinion flange. At the same time I wanted to go from a 3.7 diff to a 3.54 as the 3.7 was just too frantic (1:1 5th gear). I measured run-out at the rear of the tail-shaft with the 3.7 still in place and found I had 15 thou. Everything on the interwebs said that 5-8 thou was max allowable but I wanted to try the 3.54 diff before worrying about the vibration so thew it in and then checked run-out again.....guess what run-out went to 7.5 thou and a test drive revealed the vibration was completely gone at speeds well over 100 kmh (closed course of course!). Only once I had this sorted did I really appreciate how smooth the car now was, before it had a very subtle vibration that you could barely feel until you hit 100 kmh when it became really pronounced. So why had the run-out halved and the vibration disappeared when I changed diff's? The pinion flange on the 3.7 diff had a 3 thou run-out and that when extrapolated forward the length of the adapter increased to 8 thou and then further forward on the actual tail-shaft resulted in a total of 15 thou....which was enough to cause the vibration. Im sure the 3 thou at the pinion flange on the 3.7 diff wouldn't be an issue in the standard Z set up but it certainly caused an issue for me! Anyway good to have the vibration fixed.....until I noticed a pool of oil under the car after a test drive and a closer inspection revealed the pinion seal was pissing out a quick trip to Bayswater Bearing secured a new seal. Undoing the pinion nut bent my breaker bar and once I managed to get the flange off I removed the seal....only to find a second seal in behind the first one. I've seen some bodgy shit in my life but seriously..... one seal rammed in on top of another? ? The 3.54 diff is certainly a more usable ratio then the 3.7 but I still might try a 3.36. Once I have ratios sorted I will invest in a suitable LSD as at the moment the lack of grip is ridiculous Edited December 10, 2017 by KatoKid Quote Link to comment Share on other sites More sharing options...

George Posted December 13, 2017 Share Posted December 13, 2017 Dave, I highly recommend getting some professional photos taken while it's all fresh. There are plenty of photographers that would do it for free even to use in their portfolio. ScottyD and CBR Jeff 2 Quote Link to comment Share on other sites More sharing options...

Hi Dave, you mention that 225/50/16 were to big and you went down in size. What size did you end up going with? I have 16x8 wats "0" offset and would really like to learn from your experience.

KatoKid Posted December 24, 2017 Author Share Posted December 24, 2017 Hi Jeff. Caveat: All that follows is based on my ride height (just above the 100mm limit) which is pretty low and 16x8 "0" offset wheels. If you run standard ride height or slightly low you may get away with 225/50/16. As I said, I had interference on the lip (rolled) of the rear guards and the back edge of the front valance panel with 225/50/16 on 16x8 "0" offset wheels and it was pretty severe. On the rear it basically sat on the guard at rest and on the front I couldn't get past 1/3rd lock without the tyre picking up the lip on the back edge of the front valance panel. It just wasn't drive-able at all. Bridgestone don't do a 215 in the RE003's so I had to go down to 205/55/16. I was skeptical when the tyre shop suggested this as I thought it would look too "tucked" (aka Stance works) but it works fine and looks good as the rims sit pretty well flush with the lip, you still see the wheel size and dish but the "tuck" provides the badly needed clearance. I've done 1000km now and haven't heard any rub but a closer look just today confirms a little rub on the rears (up inside the guard not on the lip itself). and slight marks on the back edge of the front valance panel. Even if I could have got 215's I doubt they would work, as far as I'm concerned 205/55/16 is the absolute max size with this combination and ride height. If I had my time again I would definitely go with 6x8 + 4 offset wheels. Lower profile tyres may buy you more room but its more a function of width than height.

jeff43 Posted December 24, 2017 Share Posted December 24, 2017 Thanks Dave, That is exactly the info I was after. If it wasn't for your personal experience and seeing that tyre size on the car I wouldn't think it would look right. I will be going for a similar ride height so I will lock in some 205/55/16's as my tyre size. Thanks again, this saves me from doing the trial and error approach.

KatoKid Posted December 24, 2017 Author Share Posted December 24, 2017 No problem Jeff. I was lucky the tyre shop was pretty good about it and they had no issues with swapping at no cost. Quote Link to comment Share on other sites More sharing options...
