e30's in competition.......can u help me@uni??

[ChizFab]

im doing my final year project in mechanical engineering at the mo and i need to get in touch with some people who race e30's!!

let me explain, you see my project is bassically stress analysis, amongst other things, of adjustable track control arms on bmw e30's.

so...... who knows/is someone that competes, at any level, with an e30??

even if u know a site of a racing series or watever, at the moment anything will help!!!!

Hi

Speak to the bmwrdc.co.uk , check out SELOC.co.uk

Also e30m3performance.com and drop a line to gustave & also put a post (or i can for you) on s14.net

cheers mate il follow all those up!!

I should think all those poxy speed cushions are enough to test anyones tracking arms

What do you need to know?

[ChizFab]

well im basically after any/all information anyone has regarding the setup and adjustment of the front suspension but mainly camber for competition.

for example any calcs, graphs, notes made regarding what changes did. also how its adjusted, any details about the suspension components used and who makes em, there properties for example what material they made from etc...

Have you tried writing to manufacturers? or a race team? there is an e30 racing series in australia i think. when i did an assignment on high performance pistons i wrote to a company who made them and they sent me a shed load of info and i got a pass with distinction even though it was handed in 6 months late!!

I do not know if that will answer your question but let me try explain what I do for setting a front suspension. Especially camber.

When a car is driven in staright line and the tire is flat on the ground, it wears equally across the contact patch. Drive that same car continuously in cercle, and chances are that the outside shoulder of the outside wheel will wear out more. It means it works more than the rest of the tire. Only a small percentage of that said tire works to the fullest, while the remain is underused. How to we know how hard the tire works? Easy. It only requires a pyrometer and a track.

Have the driver do a few hot lapses and without any cooldown lap, have him pit. Measure the temps on all four tires: outside, center, inside. You should read temps that are linear between the outside and inside. Let's say that if you read 100Ԛ° on the inside and 200Ԛ° on the outside, then the center should read 150Ԛ°. If it reads 120Ԛ°, then it means the center is under inflated. Inflate it until the center is a median value.

What does it have to do with camber? Let me continue. Whena tires reads linearly but has the outside shoulder works way more than the inside, it means the tires doesn't work equally across the contact patch, and then camber settings should be changed. If outside works too much, then add camber. Add some, until the difference between outside and inside is almost niil.

Hope it helped.
