I have a second hand RB5 SP2 in the for sale section for £115!
Having tried the B4 Vega and the RB5, I went with the RB5 as it had all the team driver support and the one I drove was just awesome. (Matt Owens old car)
Never looked back since and would never sell it. (The one for sale is one I kept for spares, but they dont break!) I dont ever change set-ups and its good everywhere.. The two other lads I race with have both bought them too!
Expensive they are, but the amount I have saved in spares over my old cougar is mental... they are just so solid and the shocks are just awesome..
Never used the C4.1, but they seem to go very well, although they dont look very pretty with the shell off compared to the vega..
