Personally I think they are beyond economic refurbishment, but would make a fine set of build wheels, with the added advantage that 2 of the tyres were only replaced last September so have most of their original tread remaining, so could be re-used further down the line.
Tyres are 195/50/15 Toyo T1R which I've found good for my 'everyday use' with occasional trackdays.
Wheels are Inovit Rapid 15x6.5 ET38 Multistud fit (4x100 and 4x108) which weigh ~6.5Kg without tyres. Includes 3 spigot rings for Ford hubs (4th one broke up on removal so has been binned).
Wheels themselves are a mixed bag; in order from worst to best (pics of damage below):
No1 has significant scoring to the spokes & machined edge + >80% worn T1R
No2 has surface marks to the spokes and some scoring to the machined edge, missing centre cap + >80% worn T1R
No3 has a short section of damage to the machined edge + <10% worn T1R
No4 is undamaged + <10% worn T1R
£75 collected from Warwick (Tyres cost me ~£90 last Sept)
