ive just sold my b4 as i tryed a mid mount car and preferd its handling.i cannot see the point in buying a conversion kit at £160 when you could get a new mid mount car for that and sell your b4 to recoup some money.only way i would convert it is if you did it by buying the parts over time for a centro ,neal lewis is selling nice well made chassis on here then buy other parts as you go along.up to you,some are still very quick with b4`s it just didnt suit my driving style(style in the loosest sense of the word
)
