If this is for a 1991-1998 Clio RSi then this is WAY, way over the top (even for Renault actaully ).
The front springs should be about £70 maximum really - decent aftermarket ones cost circa £50 plus (for lowering). The shocks sound reasonable. But if youre willing to fork out about £300-400 - which is still less than Renault - you could have Spax or Koni shocks and springs all round to make your car handle like a dream.
The front bearings are way over game agian - about £90 per side is par at AA/non franchises. Discs again are well over the top - £450 for all four is far, far too much. Again, pattern parts (e.g. Halfords) will costs you about £100 for all four - or you could get race-spec ones for £250 all round.
N.B. You will most likely need rear wheel bearings if youre having new rear discs - theyre pressed in by the disc apparently.
I reckon you could get all this done for circa £500 fitted at a local garage. Ask some yokels in the trade and find out who to trust. AA Garages or similar will be near in price - you get 10% off if youre an AA member (£39 - could be worth it if your bill is over £390!
Just please dont pay this sort of price for this work. You will not be getting any better quality parts, service or guarantees.
