I have hardened the rear with bigger torsion bars + bilstein b6 and now I need to make the front stiffer.
Currently I am using bilstein b8 + eibach springs on the front. I can not put coilovers (because of regulations for stock class in the local time attack championship). So I have to deal with the standard diameter springs, but none of the vendors provide the spring ratings for the standard lowering springs.

My question is what are the stiffest standard diameter spring that can be fitted to my 6? Or any advice in this direction would be helpful.

Custom? Where/Who can manufacture custom springs? I am afraid that the price will be too high?

Have you tried contacting the spring manufacturers directly? For example, demontweeks won't know spring rates but Eibach should. Whether or not they'll give you them is another thing...

Or failing that, springcoil, both are sheffield based and do custom springs.

I'm in Bulgaria and here I have not heard for custom springs Smile Some people just cut the original springs to make them stiff and low, but I dont like this. Others buy only lowering kits or coilovers Smile
However I've sent a question to coilsprings and will see what will happen.

Meanwhile, what exact spring rate would be best to match my current setup (1100kg, front - B8 dampers, rear - B6 dampers with standart ARB + 25.5mm torsion bars) ?

You need much less rear spring rate or better dampers.

Agree with welshpug, those dampers aren't up to the job. I'd be looking at 450-500lb springs to match your rear end

Yep it's in the "financial" plan to change the dampers too Smile
Currently the car is very jumpy in the city, but on the track it's not so bad, except a lot of oversteering when lift off the gas pedal.
