Hi All,

This time last year I was running a V8VR SS, but got so pissed off with what can only be described as an abysmal gear change I got the hump and chopped it in for a 997 PDK (I can hear the screams already).

That said, whilst the Porsche is undoubtedly a tremendous machine and the gearbox is phenomenal, the whole car doesn't feel special in the slightest, and that's not what I want when paying top money.

So I'm back in the hunt for a V8S Coupe, but now i'm torn between a manual or the SS2. I hear the SS2 is far better than the previous version, but still pretty bad in comparison.

So the BR twin plate and lightened flywheel............

Would having that fitted entirely remove the nodding dog symptoms when driving in both D and S, and make it closer in experience to say a DB9 (a smooth automatic), or would it just reduce it. I also found mine to be hard to drive when cold, as it didn't want to shift up to second until moving nicely, which made the whole thing really jerky.

Also, I believe it would entirely remove the BBQ sensation when reversing up inclines.......is this so ?

So whilst i really want another V8, I need to be sure that i'm not about to end up in the same position as before and getting the hump.

Any thoughts or advice would be gratefully received.

I had exactly he same issues/questions and the short answer is that the BR clutch and flywheel solved it for me -about 1 yr and 6000 miles on using the car as my daily driver, always with sportshift, id say I experience the very occasional judder when cold but that's all - and I live on a very steep hill - with reverse parallel parking a regular feature of life.

As you can see from the post below, it didn't go 100% smoothly in terms of timings but I was clearly beyond delighted with the immediate results after the upgrade and remain a very very happy customer. I think the clutch has turned my car into hthe practical 'keeper' I wanted.

Thanks for this info, it sounds like exactly what I was looking for.

Obviously I need to speak with BR and go from there, but would you mind telling me the ballpark £ for the clutch and flywheel (all subject to change obviously).

The last time I enquired it was £3,600 (Nov 2014). I am thinking about getting it done on my V8VR Sportshift 1 in the summer.

Just a point to note for all Sportshift 1 owners here, once a month approx I start my car from cold 4 times in succession (doing a "clutch learn") and this makes a huge difference to the Sportshift in my car.
I also do a "clutch learn" everytime I start the car from cold (with ALL electrics off) as recommended by AM.

When my car was in AM Edinburgh recently they flashed the latest software to my Sportshift module, but I cannot say I have noticed a great difference, the key for me is doing the cold start & clutch learn 4 times in succession approx once a month

It won't remove the nodding dog in D, it will improve it, fundamentally it will never be like a DB9's box as it does not have the torque convertor. Its a robotic manual and needs to be drive like that (a little lift of throttle on a gear changes makes a massive difference)
It will get rid of it on the paddles.
On the reversing a point to note is ASM2 has a much better reverse gear, the manuals are ALL STILL the same as ASM1's ratio. wink
I'm pleased with the improvement it made to my ASM2 box once it wasn't a box full of bits (thank you Ian Minnards frown )

Great advice...thank you.

I'm pleased that you told me the manual still cooks up a storm in reverse. So have they adjusted the reverse gearing on the ASM2 then. I must admit there was a few times when reversing up my drive where I nearly flew into the garage door due to the high reverse........it would only have been a matter of time.

As for the DB9, I understand what you're saying re lack of TC etc, I guess I was more wondering whether the upgrade made it 'more' like a general auto, however I appreciate it will never be quiet as smooth.

It does amaze me that Aston haven't produced a box like the PDK or DSG.......you've only got to look on these forums to see that buyers want it. It's the one thing I'll miss about the 911.......the PDK is awesome....

yep reverse ratio is lower on ASM2/3 vs ASM1/6MT
The BR clutch package does make a BIG difference to the nodding dog it just doesn't eliminate it
I seem to recall its an issue of space, with the box being at the back there isn't enough room to get the more modern Graziano boxes used by Ferrari etc in there. (it could just be cost though wink )

I've driven a fair few of the modern "flappy paddle" boxes and ASM2 with the BR package and a lift isn't too far behind them IME. I can live with it wink

You have to remember that the V8 Vantage was originally designed for the Graziano manual gearbox and the Sportshift gearbox (in all 3 variations) is basically a Graziano manual gearbox with hydraulic modules bolted onto it and a set of gearshift paddles
For Aston to engineer in a new PDK or DSG box would not be worth the effort or cost given the lifespan remaining of the current Vantage

Yeah that's a fair point, although if they fail to deliver something similar to the PDK when they replace the Vantage, then there'll be no excusing that in my book.

The thing I do not understand is why Aston have never made any attempts to improve on the Sportshift gearbox (especially ASM 1), surely if BR and DAE offer an upgraded and much improved clutch then Aston could have offered their equivalent.
At least this would have given some recognition that they offer existing owners improved technology

I suspect you will find the well liked Merc auto mate to and AML branded AMG engine going in
I know the current torque tube is also used by mercedes so that ought to make things simpler wink

AFAIK the BR guys currently offer a product that was "evaluated" by the factory and didn't get approved
by the bean counters wink

Don't DAE sell the AML twin plate clutch used in DBS?

I am pretty sure BR actually designed their own clutch in conjunction with a manufacturer.
