Re: E36 Track Day Hack (v2)
Drained the mineral oil at the weekend and replaced with the usual SemiSynth I use, along with a new filter. Car runs cooler now (oil temp) as expected.
I switched the main cooling fan relay to use a permanent 12v source, and put in a manual override switch in the cabin so even if the car is turned off and the coolant is still too hot, the fan will continue to run until it drops enough. I also reprogrammed my oil temperature gauge to get the range of values I wanted, so I can quickly work out the exact temperature in degrees when I need to.
With a few trips coming up, including a day at Oulton, I wanted to get the alignment checked again, especially to check the front as the wishbones/balljoints have been changed since then. It was previously done at Blink Motorsport, who were recommended at the time. I tried to get another appointment but had no joy over the space of a month, no answer on the phones and no replies to e-mails, where previously I got very quick responses. Anyway, I decided to go elsewhere - a place in Liverpool with a Hunter system who just specialise in alignment, nothing else.
To recap, when I previously went to Blink, the completed printout gave the following:
Front Toe: 0
Front Camber L + R: -3.0deg
Rear Toe: 20min Total Toe In
Rear Camber L + R: -2.0deg
Which were the settings I provided and wanted at the time. This was September 2013. Drove straight as far as I could tell..
Now I knew the front toe would be out, as the whole front subframe, wishbones and balljoints have been swapped. The rear end has not been touched with a spanner since then, every thing is 'as it was', and at the time everything was brand new. Needless to say when we got the initial readout today I was quite disappointed..
Front camber is different L/R, and the wrong value. Top mounts have never been touched since it was originally set up. Rear camber is the wrong value on the rear also, but equal. Apparently a common mistake if the Hunter kit isn't calibrated properly... Front toe is out as mentioned above, but rear toe is p*ssed across the axle, even though its total is near enough correct (20min total). Caster can be ignored as its not adjustable.
Anyway, for now I just wanted the toe correct, so its not chewing through tyres. Did not want to go messing about with the camber (as its not a simple job on the fronts, takes time with fiddling). We got there in the end (Front camber is actually equal but we didn't do a final printout once the car had rolled off and back on)..
Eventually I will go back and add more camber, as now I know the true value its not really enough, probably 2.75F and 2.25R, but we'll see. It now drives how it should, much better than before (which I thought was OK anyway), and I'm questioning whether it was ever 'right' when I had it done at Blink. Looks like they got it 'near' then accepted that IMO.
I don't really understand how hard it can be to find somewhere that you can trust to get it perfect for the money these places charge, first time round? I've heard quite a few reports of various places in the NW doing poor jobs of late also!
