Huge oversight/laziness from Renault here. When the specs were announced I got jumped all over by the RS fan boys on this forum for highlighting how out of touch Renault were by forcing customers that wanted an RS to choose a single suspension setup, and worse determining the traction a customer could have access to based on their preference of ride quality, i.e. limiting LSD to stiff Cup chassis only.
RS are stuck in the past, hot hatches have moved on, prices are high and competitors like for example Hyundai, Honda, Seat, VW etc.. respect the fact that the customer may want comfort suspension when cruising around with the missus/kids/etc, and then a stiffer setup for a back road blast. Limiting LSD to stiff suspension only is madness.
The car looks, IMO, the best hot hatch on the market by a margin, and as I'm changing this year it's definitely on my list. However, there are none to test drive in Ireland therefore I'd have to make this insane suspension choice blind. I'm leaning towards Sport chassis, manual & 19" wheels. Although I realise 18" will make it more comfy on bad roads, the Renault Ireland configurator doesn't have 18" option, also the car looks amazing with the 19" so hopefully the Sport chassis would still be compliant and easy to live with.
Concerns are:
i) Traction without LSD. What is it like on a wet, bumpy back road? always spinning up the inside wheel out of slow corners?
ii) Comfort, what is the Sport chassis like over poor quality back roads? (e.g. with lots of filled potholes, i.e. therefore not flat)
iii) Engine. The carwow drag races were very concerning. I drove an i30n which I found quite lethargic and heavy (and not refined enough overall for the daily commute, road noise etc), but it still beat the RS. The RS did unfortunately get whooped.
iv) Renault customer support. Very worrying to hear the disgusting way in which the user 'Del115' has been treated by Renault.
I'd love to hear any thoughts from owners, both good and bad, particularly Sport chassis owners?
Before anyone says, buy a Civic Type R, i need 5 seats, and I want a handbrake.... gravel, ice, muck, and no handbrake, WTF would a man do
