What's said in the advert is :
"The chassis and engine were as the Mark IV, but the body was both stronger and lighter than the Mark IV"
So my take is its the body (and not chassis) that's reffered to as stronger & lighter in the advert.
From my chassis Instruction book for the CRS
1350kg is the Gross Vehicle weight
1120kg is the kerb weight
Front /rear distribution is 560kg even
Maximum permissible axle weights are 700kg front 800kg rear
(I have my MOT this week so will get a weight from that to compare with the chassis book)
This particular car is a club members car I believe and with the 15" wheels & CR6zz (£2k package) , colour scheme, trimming its very good value.
I think Redline just sold the blue CRS 9502 as its appeared up in Aberdeen-would have been a long test drive.
