My set up is a rather basic 280mm 4 pot set-up in comparison to yours tho.
Well done! Please post some pics when you get a chance.
I haven't bothered to put my heat-shields back yet, and so far haven't had any problems. But I'm keeping my eyes peeled for any signs that the rubber boots on the track-rod ends have started to burn. Without the heat shield the discs seem to cool quite effectively, but I'm prepared to put the shields back if I have to.
Remember, the idea is to choose your spacer so that the centre line of your wheel sits as close as possible to the bearing centre-line, which is 24mm deep into the hub (with disc in place). That's why the specified ET on the front of the E30 is 24mm. This will maximise your bearing life.
Since we are probably all using different rims, its likely that we all require different spacers. Unfortunately it's not always possible to get the wheel centre-line to line up with the bearing centre-line (sometimes the caliper strikes the inside face of the rim, or the tyre smacks the strut), but its always good to get the centre-lines as close to each other as possible. With the rims that I have on the front of my car at the moment I am out by 11mm, but I don't think the bearings are likely to fail catastrophically on the track, so I am happy.
I thought Isotta made a 4-bolt, PCD100, 10mm spacer, but I could be wrong? When I initially measured up I thought I would need at least a 13mm spacer, so I bought 16mm spacers with the intention of taking off 3mm. But in the end this figure came down to 10mm, which is better.
The Isotta part number is S1026C and can be found at
http://www.isotta.com. To anyone else reading this, don't use these spacers unless you are certain that they
won't result in an excessively reduced ET when added to your wheels. Even if you are prepared to change your bearings regularly, you
don't want to increase the scrub-radius on a track car as this will result in brake-steer.
Nicely done!! I'm in awe! Would love to attempt something like this one day.......
but cant find them anywhere. ds 2500 is only bringing up pads. wheres brianmoore... he knows everything about everything.
