My MO5L on show.

BTW,

I do have a rear swaybar fitted, however it is disconnected on one side, so it does not work.

Having been only involved with TCS racing for almost the entire time of racing Minis, I have fallen behind on a lot of the new diffs etc. My fault entirely as there have been plenty of posts, which I haven't read, cause it was not something useful at the time. Recently, there are a couple of venues that are starting to run Minis again that allow some "outlaw" stuff.

I have a couple of M05s that sit neglected on the shelf so would like to convert them to "outlaw" racing. Please understand, I mean no disrespect with the term outlaw as that seem to be preferable to "cheater". While TCS racing is something I will continue to do, it can be a little constraining with it's Spec tire and strict rules on everything else. However, taking a TCCS car to an "outlaw" venue, would be like taking a proverbial knife to a gun fight.

If I haven't pissed people off with the term "outlaw", I was hoping some of you would bring me up to date on the new diffs. Also would like some info on some of the new small diameter tires, particularly for carpet racing. You can PM me since there's no use reposting a bunch of stuff.

Calvin, kudos for your recent win. Hard work does pay off. Let me hear from you cause I leave the Facebook stuff to you young people. Did some trading on the stock tho.

Local to me in the UK, carpet tyres are Sweep pre-mounts (33 front with glued sidewalls, 25 rear), diff is 3Racing with 5K oil.

M03 camber issue
 
4 Attachment(s)
I was wondering if anyone out there has come up with a solution to reduce the amount of Camber both front and rear in an M03?

I adjusted my ride height down to around 6.5mm and the camber is rather excessive, like 3deg.

Attached are some pictures showing the front and rear. 1 & 3 are the front and 2 and 4 are the rear.

The simple solution is to adjust the ride height up but this is not desired. If there's no solution i guess I'll do more testing to see if the ride height or less camber provides better performance.

Has anyone got any idea why the level of front toe out would increase after two meetings on my m05? I haven't adjusted it. I initially set it to around 2 degrees, now it looks nearer to 5! I placed a couple of washers in the steering rods to set toe and they're still there. Could it be worn ball cups?

The M0 kits have terrible bump steer which causes toe change. Make sure your ride height has not changed. But it could be slop in the ball ends.

1mm washer between ball cups = 2deg toe out at 5.5-6mm ride height (stock camber link).

Toe out / camber angle will drastically change depending on ride height using m03/05 chassis.

Yeah racing makes an optional set of camber links which allows for full adjustment.

Another idea would be to use smaller tires and keep your ride height stock.

I'll have to look at the yeah racing parts.

Can't change tires. We've decided as racers in this area to make the Mini class as spec as possible to keep racing simple and close. So we're using the TCS rules with further restrictions.

Here's our rules if anyone is interested, CTMP, so far it's working out very well. The class is growing weekly with new drivers.

Yep, 1mm washer used to give me roughly 2deg toe out at 6mm ride height, it now gives me nearer 5deg. What's going on?

Check that the plastic parts (steering uprights, steering cranks etc) haven't bent from an impact - the plastic Tamiya uses will bend rather than break.

2hundy 07-19-2012 02:53 PM

You hit the nail on the head there sosidge.

Only after comparing the uprights to my brother's m05 did I see the bent uprights.

Both left and right are bent the same amount, hence not spotting it in isolation.

Thanks.

Tamiya 54182 adjustable upper links for the rear work well. For the front I've never found the need but there are some solid alloy upper links in slightly different lengths, Tobee Craft from Japan make them.
