16 inch wheels?

[improvedae86]

I really think your reading far too much into this

The brake size on the N2 cars at that stage was locked at that stage
so going to 17" rims didn't equal people fitting bigger brakes.

If you want to go on about slip angles i suggest you read lots of Lotus's early 80's information on this. Mostly geometry and track , roll centers , camber , caster has far greater effect on slip angle than just tyre size.
Why do most manufactures bother with constant suspension changes on vehicles of the same weight ? why don't they just stick on larger tyres. Audi a4 series is a good example of this. Same rough weight , same tyre size but each model has small changes to the suspension geometry.

If people want a good basic idea on slip angle
http://en.wikipedia.org/wiki/Slip_angle

One point that is really missing , is the ae86 under-tyred to start with ?

"Wider tires require a smaller slip angles change to produce cornering forces. THAT is what makes the difference in lateral grip, longitudal grip, stability and driving feel. Contact patch size has nothing to do with it."

Where we commenting on the same width tyres not wider tyres?

Sorry if I sound harsh. I mean no offence but since you a engineer? maybe give us the maths on the standard car vs a 16' rims size car of equal width .If you want use suspension analizer , lotus or what program to get the results. Since the original question by the thread starter was on improving there braking performance it will be good to see the de-acceleration graph between the sizes.

I know its going to be worst without lots of changes , so maybe once again this thread should be related to people using 16" and the changes that they have made and there results
