Mark, any weight numbers 
985kgs.
I'm quite pleased with that.
Brands was good fun yesterday, but busy. I'm not sure if Track-Days book more cars on track than MSV but it certainly seemed so.
The car was great although the tyres seemed to struggle with the heat and lost grip after 3 or 4 laps. The front discs threw in the towel in the final 20 minutes, so I've got to order some new ones. Any suggestions? I'd planned on Tarox but tbh, I'm not sure they're worth 4 times the price of the alternatives?

I put 17'' Azevs on my M3 (purely because I couldn't find any 16's) but they look better than those imo.

The M3 is capable of running 18's (as per Sport Evolution Front Wings etc). Problem is ride height, that car in the Link above is very high off the ground.
Ps, not meaning to be horrible, but I honestly thought your car would have been lighter, dont know why.

I think there was way more fuel than I had at first thought, plus I'm questioning the accuracy of the scales I used. I'm going to another weigh bridge over the weekend, so fingers crossed.Demlotcrew wrote:I honestly thought your car would have been lighter, dont know why.
I managed to source an alloy, foam filled fuel tank today. It's a 30 litre FIA tank with fuel level and also came with a swirl pot & pumps. We can now take the OE tanks out, with the boot floor & rear bulkhead. We'll do all that when the M3 arch kit goes on.
I've arranged with Joe (Aversracers) to do my M52 conversion when I go to Cornwall in September.

See im not convinced the tank is a good idea. The OE tank doesn't really weigh that much and its in the best possible place. Anything else is just a compromise in my opinion.
I really need to get my turd on the scales!

You might be right re the tank. My intention had been to work out the best position when I did the corner weights, in an effort to offset my own weight. I also have a problem with left hand corners once the fuel level gets below one third full, although I imagine a swirl pot will cure that so long as there is a constant enough feed?
I want to replace the front pads, in the Wilwoods, but am uncertain which type they are? Can any of you guys recognise them? Also, what pads would you suggest?

New discs arrived yesterday.

those Wilwoods look like Dynalites to me mark. could be wrong.
are you looking to go bigger wheels?
you should be able to get 305mm discs with slim caliper under those racelines
I am running a near 300mm disc now under my TD wheels.
have you looked at those hubcentric spacers that bolt to the hubs and then studs into the hubs? I have tried this and I can now run the BBS RZ 15 inch too as lots of caliper clearance. still sits nicely in the arches and much safer than before.
good weight i think you have achieved there buddy.

Dynalites.....you could be right. I found the number of the guy who sold them to me but is constant voicemail.
I'll try Dynalite pads and just have to swap if incorrect.
* ordered Hawk HB pads from Cambridge Motorsport. Anyone else use them?
I'll be going up to 16'' rims once the M3 arches go on. Right now, the brakes are OK tbh although that might change once the M52 goes in and I have another 50 brake to play with.
I ran some of those adaptors on my e21 but always worried about the effect of the wheel bearings. Am I worrying for nothing? They'd certainly help me get a better choice of rim to fill the M3 arches.

Brands yesterday was great fun. There were several nice e30's out and it was good to follow a couple of the quicker ones, in an effort to see where I lose time. My best is a 59 dead but I could do with having the suspension set-up properly and running a little more negative camber. I'm also a bit of a lump for my poor little m20 to drag around.
Did anyone get any pics? I got some video but need to edit it first.
edit - my best was a 59.7 with a potential best of 59 using 3 best sector times.

Hawk are actually not a bad pad brand, I used them once and I thought they were pretty good!

That is at mates rates.

I can't tell you how much happier I am with my eighty quid ones.
In fact, I need to get my arse into gear and go fit them as I'm hoping to be doing a sprint at Clay Pigeon on Sunday.
Can I just ask if my times at Brands are reasonable for a car like mine? It's only fun but it would be nice to think I'm going in the right direction as I only started doing this stuff last year.

I have no idea, I have never timed a lap, but 59 seconds sounds ok!
Well I removed the old, warped discs today and cleaned up the struts. I bought new drilled / grooved discs from Tarox but the Hawk pads were for the newer Wilwood Dynalites so don't fit. Cambridge Motorsport were very quick to try and sort the mistake but the only compound they could supply today were blues and they simply won't suit my needs. I'm going to have to wait 2 weeks instead.Demlotcrew wrote:Hawk are actually not a bad pad brand, I used them once and I thought they were pretty good!

My current pads, although worn, do have just about enough life left to see me through the weekend. I'm doing a sprint at Clay Pigeon circuit in Dorset. Once I'd fitted the new discs and bolted everything back together, it all looked far better.

I still need to get the corner weights and geometry done though.

Mark, I agree those groves are facing the wrong way. 
This is from the Tarox website.

However, I've found different opinions on every forum, manufacturers website etc but nothing definitive. I'll ring them tomorrow and ask. It does seem that there are advantages and disadvantages to either direction.

Just spent half hour ringing AP, Tarox etc.
1) It's Saturday - Doh!
2) I did get to speak to some people though and general opinion is that the 2 pics above are correct, HOWEVER, the effect is negligible and the only important thing to check is the direction of the internal cooling vanes, which are 'sided' on some discs. Mine aren't though.

Mark, different disk face types offer different functions.
AP disks are sided, and the groves on my disks leave a very interesting pattern of dust on the inside of my wheels, its clearly a functional design for deglazing the pad and keeping the groves clear.
The AP blurb says.

I would contact the manufacturer of your disks as tell them your application, they should then advise you of the orientation.

AP Racing wrote:Disc Grooves and sometimes cross drilling are normally used on all racing brake discs to clean the surface of the pad & allow gases produced to escape. In doing so the friction characteristics are modified. Different groove and drilling patterns affect the friction characteristic in different ways, some affect overall friction and others the bite or release characteristics & therefore the best solution is not necessarily the same for each application.
AP Racing is constantly developing and refining disc face patterns and new variations will be introduced from time to time. The most popular face types are detailed below and the page opposite. N.B. Not all Face Types are available for every disc.

I would contact the manufacturer of your disks as tell them your application, they should then advise you of the orientation.
Finally got e-mail back and simply says - installation is correct.
New pads arrived this morning so going to fit tomorrow if I get half hour free.
My car has an E36 rack and I noticed just how far forward it has to mount, compared to an OE rack. Are there any negative aspects to running this rack? The reason I ask is that I am unsure which would be the best LHD option for me? Can anyone advise me please?
Looks like this weekends hillclimb at Lostwithiel is to be cancelled due to the bad weather they've been having in Cornwall. The field usually used as a pit is waterlogged.

Mark do you have a link to the sprint series? For various reasons I've only got to do one race meeting so far this season, if there are regular sprints at Clay Pigeon I may have a bash at it for a day out and to get to use the car a bit more (no idea where CP is but can't be that far away from me if it's in Dorset).
Cheers

For sale - E30 320i racer project - sold.
Clay Pigeon is near Dorchester, so not far, although I think that's it for this year. I don't do a championship but just odd rounds here and there. This weekend would have been Lostwithiel in Cornwall but rain looks likely to stop play.
There are plenty of events in Cornwall though.

Can you see which way the vents inside the disc and facing? The most important thing is that the vents are spinning the right way to 'expel' the hot air as the disc spins.

Would have to find the car in the garage firstBrian28 wrote:Mark do you have a link to the sprint series?
