I'm going to fit one of these to my rear line, pretty good price.

Adjustable bias valves aren't allowed under IVA regs as far as I'm aware.

This is a good point. RTFM.

I really don't want to be changing the bias valve at this point if I can help it.

I was so close to passing overall efficiency (3% below the limit), that I'm sure just giving the brakes a damn good thrashing and getting them bedded in properly will be enough to get through the test.

Just spoke to my friendly garage across the road from work and he said he'll check it on his MOT rollers for my free of charge
So a drive to work next week with plenty of left foot braking might be in order!

Forgot to mention in my write up yesterday. You NEED a bike helmet with these cars. I set off with just sunglasses on, but had to stop and switch to my helmet a few miles in because I was struggling to breath above 45mph

I did a bit more research and if you do find you need a new valve a Fiat Uno valve seems to be a good choice and used on quite a few builds. It can be modified to be adjustible after IVA too just by changing the way you mount it.

Hi John,
Sorry about the fail....
Well I guess you can now concentrate your efforts on the things it failed on and should be an easy fix.
So come on what's it like to drive one on the road for real...
To be honest I don't think I would have the b**ls to drive it to the test.
