I also got a quote of APS, who can supply them.

Please find below details for the prices you have requested.
Bilstein Sprint dampers front: £272+VAT pair
Bilstein Sprint dampers rear: £178+VAT pair
H&R springs: £145+VAT
Neuspeed 22mm front ARB with bush kit: £145+VAT
Neuspeed 19mm rear bar with bush kit: £175+VAT
Adjustable tie arms: £275+VAT
Wheel spacers, based on 10 or 15mm rear and 10mm front: £177+VAT
In terms of fitting it would work out to be cheaper to do all in one go and
we would charge £200+VAT.
The final total of all parts, labour and VAT works out to be £1841.22.
Hope this helps
