just wondering what weight the e30 race cars in the miltek (or whatever) championship run at.
im lookin at stripping mine totally out anyway and just wondered what weight i could expect and thought this was the best place to ask..
Race car weight.

i think the regs for one of the BMW championships has 4 categories with HP to Kg categories so for example if you are 260 hp but weigh 1300kg youre lower rated than 220hp @ 1000kg.
this may be the Kumho one don't remember the others name
reckon handling is everything power to weight is second

The race race series with the four power to weight ratio classes is the Kumho BMW Championship.
The 2005 Milltek Sport BMW challenge has only one class for E30 318i and 320i with minimum weights of the cars at 970kg and 1030kg respectively without driver. There are also minimum weights with driver which must be met.
Regulations are here: http://www.selocmotorsport.com/
you could possibly do better than the above if you don't need to meet those regulations.

The Kumho classes are as follows
Class A 215 bhp/ton
Class B 195 bhp/ton
Class C 175 bhp/ton
Class D 145 bhp/ton
All weights are with driver in full racing gear & all bhp is at the wheels so for instance a class D car that weighed 1125 would have to be a max of 164 at the wheels (around 195 at the fly).
If you strip literally everything including the underseal, fit a T45 cage & go for lightweight wheels, seats etc it's possible to get these down to 990-1000kgs but you'd have to be religious to the point that it started costing quite substantial extra monies. But, a light will outhandle & outperform & outlast (in terms of mechanics) a heavier car. Weight is the ENEMY!

Matt, the Milltek min weight figure is a good target, we designed it around the min weight of a basic stripped down car. No excessive expenditure on super light stuff, just taking everything out that didn't need to be there.

I run a 2.7 powered former 320i in sprints & hillclimbs. Weighs about 1030kg stripped out. No lightweight panels. Biggest job was removing the sunroof.
