Zeezeebaba Posted September 23, 2014 Posted September 23, 2014 Ok so I'm looking at a coupe, however I have a bloke popping over in a drop top later. I quite like the look of a convertible and my daughter would love it.My concern is the usual worry of torsional stiffness and how it affects the chassis. Any input welcome on how they compare, thanks. Quote
Commander Posted September 23, 2014 Posted September 23, 2014 I'm sure somebody said the Zed was designed as a 'vert' first and the Coupe design followed? And that the vert was actually quite decent and doesn't suffer with the usual problems you get when a coupe design is chopped up to make it a vert? Quote
brillomaster Posted September 23, 2014 Posted September 23, 2014 That can't be true, the vert looks bloody awful with the roof up! the coupe looks a lot nicer. also, does the convertible have the trademark z rear strut brace? if it doesn't, then that bracing must be put somewhere else in the car.

ZMANALEX Posted September 23, 2014 Posted September 23, 2014 You will have no issues with the Roadster regarding torsional stiffness as you put it. I track one and added bracing, however this would not be required for road use. Alex. 1 Quote
cmck13 Posted September 23, 2014 Posted September 23, 2014 Agree with alex, but do not try to beat any world records with the roof down, very un-aerodynamical in the wind tunnel. It doesn't matter though its what you prefer. Quote
Zeezeebaba Posted September 23, 2014 Author Posted September 23, 2014 I think I will stick with a coupe. Thanks for the input.Just need to shift the M3 now. Quote
Ekona Posted September 23, 2014 Posted September 23, 2014 I tracked an '06 roadster with full Summit underbody bracing back to back with a HR coupe. The coupe was far superior, and that was the exact moment I started turning away from convertibles. That said, I agree 100% with Alex: On the roads, at normal speeds, you will never notice any difference. I certainly didn't until that single trackday, as I was more than happy with my old ragtop.

The Chubby Ninja Posted September 23, 2014 Posted September 23, 2014 Agree with alex, but do not try to beat any world records with the roof down, very un-aerodynamical in the wind tunnel. It doesn't matter though its what you prefer. im sure alex`s roadster would be in with a chance of beating records with his setup Quote
Commander Posted September 23, 2014 Posted September 23, 2014 I think I will stick with a coupe. Thanks for the input.Just need to shift the M3 now. I'm in the market for an M3 and I'm thinking about selling my HR (Coupe, not Convertible) - got an advert up anywhere? Quote
mrt Posted September 23, 2014 Posted September 23, 2014 Sold my convertible in June. Great car and no problems with rigidity. Replaced with another coupe for two reasons. 100kgs heavier than the coupe so slower acceleration. Roof up looks less sleek. However,roof down looks great....IMHO Drove 90 % roof up Quote
Zeezeebaba Posted September 23, 2014 Author Posted September 23, 2014 Commander, I doubt my M would appeal to you. It's a manual in carbon black with 114k miles. Insp2 done in May. Rear subframe reinforcement done. New clutch and ancillaries. New vanos. New conticontact sport tyres all round. A good straight car but mileage puts loads of people off.Compared to some of the tat out there its a nice example. I've even got a replacement wing to go on as one is starting to bubble along an inch of the arch. Quote
Commander Posted September 23, 2014 Posted September 23, 2014 Well I'm after two! One nice one and one to track, so manual is ideal, I'm not too worried about the cosmetics and I'm glad to hear the RSF has had some TLC. What sort of price are you after? Quote
