Hey guys - I'm about to pull the trigger on a '15 RCF - has all options besides the diff option. How important is this option? I do not track....

 

I can only speak for myself. I absolutely love it! I do not track my car either, but i find the extra assistance in helping the rear end of this big coupe turn very helpful even on the streets. Could I survive without it? Yes, but I also do love the carbon fiber bits

 

^^ what he said. If you don't track, then the CF pieces alone should be enough to sway you

I'm sure there are many other threads on this subject too. I just had this one handy.

 

Negligible difference in weight, power and steering for the common driver.
Price difference not so negligible.

Plenty of vinyl Carbon Fiber wraps at <$100 if the CF looks are what sway you.

 

I have the TVD and on turns it is definitely noticeable. You can feel the power shift to the rear wheel. Its pretty obvious if you go and test drive a non TVD. It isn't something that you need to have. If you can find a good deal on one without it doesn't really matter bc the RCF is still considered a great car regardless.

 

I just bought my 2015 With the TVD and I wanted it on purpose to reduce the amount of understeer this car supposedly has. I have enjoyed all 1700 miles that I have driven of it so far.

 

Thanks guys - I think I'm going to hold out for a vehicle with the TVD - the one irritant is it seems most sales folks don't understand this - most responses are it has a LSD! Even ads don't really specify this. There's definitely some deals to be had so I'm being patient.
My other cars are a '15 M4 and '14 S5 so I really need an RCF!
Many thanks for all your input...

 

the TVD was full of understeer to me. the torsen was the opposite.

the rc-f comes standard with a torsen LSD. sales people are right.

 

What I noticed when I test drove my RC-F with the TVD was very controllable oversteer. I didn't test drive one without TVD though.

 

I've owned both with and without TVD - get one with TVD. Plus, the carbon fiber looks cool as hell.

 

You must love coupes. I had a 2015 S5 as well and its very different from the RC-F. Do you have the torque vectoring in your S5 as well? I did and I felt it when I was taking corners and sweepers. I am not sure about the RC-F TVD as I have not driven one. All I can say is that the RC-F torsen rear is more playful than the S5 with TVD. I think this is more about the understeer in AWD vehicles but am not sure.

 

You have to play with the settings. Normal=understeer, slalom = controllable oversteer, track = neutral and balanced. Of course, any of these settings can be combined with eco, normal, sport and sport+. I find track at home of the freeway and slalom on the streets

I meant a couple dudes were clueless about the TVD - they only knew about the LSD.

 

I do have the Sports diff on the S5 - the S5 has an APR II tune; pulley and AWE exhaust; dps - definitely a blast off the line and amazing cornering....the more I research, I think I'll hold out for the TVD.
