Quote from isf article in top gear."Both editor in chief Charlie Turner and i had one and we both still think its the most memorable long term cars weve ever run.And when alls said and done,memories are what matter,aren't they?" HERE HERE!!
It's like taking a current ISF removing two doors and sticking in a load of weight (albeit with an extra 60hp)
Strangley the bit that was all round praised on the ISF ( the brakes) saying that they were unbelievably good and stood up to track use is one of the bits they are saying is poor on the RCF - think the extra weight is just too much.
They went toally overboard in the quest for stiffness that they seem to have totally forgotten about weight.
Using the IS Convertible middle because it already had the bracing they required was insane imo - the extra weight that brougt along just was not worth it.
If the rumours are true and they make an F version of current IS then thst should be vastly better.
It's a abrasive material that is very good at getting contaminants like tar off the paint work. Needs elbow grease! Remember to use a lubricant if you decide to do it.
