you soon get used to the better revving engine and the different engine braking characteristics - which is not something you will notice after a few hundred miles of use anyway

Gordon, I experienced virtually no engine braking on the VXR (stage 2 lightened fly).  Must be to do with the turbo in some way, I don't know how though...    What I was talking about is with the NA, so if you are comparing your VXR to your NA then that comparison is hopeless anyway as they are completely different beasts.   Chill I'm not sure, but you are SC are you not?  Cam timing, forced induction, CR will all have an effect one way or the other on the effect of engine braking     Basically if you change ONLY the flywheel then engine braking will be increased as the engine will be less willing to hold onto revs when off the throttle.   Ask Goose how my NA felt compared to his...  

Gutless?

Yes I was on about the stage four which as in yours seemed to have very little. But reading other stuff like I posted earlier some seem to experience a loss just changing the fly wheel, unless they don't mention other changes maybe .

Just get it fitted...

Might be above somewhere.. but just found this...

 

A light flywheel is a popular performance modification that has distinct characteristics. The trouble is deciding if a lightened flywheel is right for your particular situation. As the flywheel is an integral part of the system, changing it can really cause kinks in smooth operation.

 

Many people think a lightened flywheel is automatically going to improve vehicle performance however the truth is that the properties of each flywheel varies. Oftentimes a super-light flywheel is not the right choice for someone modifying a car for daily use. There are plenty of options when it comes to upgrading the drivetrain, even when it comes to different flywheels.

 

 

 

 

 

Dual-Mass

Most modern cars use a dual-mass flywheel. The dual-mass flywheel is comprised of two flywheels joined together by shock absorbing springs and struts. This reduces shock to the drivetrain when the clutch is engaged, which results in reduced wear to components as well as a smoother driving experience. Dual mass designs are simply the best choice for most drivers since they are the most forgiving in design. There are upgraded dual mass flywheels available for some cars that offer more responsive shifts for people with a slightly more performance-oriented style.

 

 

 

 

 

Single-Mass

The name is self explanatory. A single mass flywheel is just that--a single metal flywheel disk with a friction surface. Single-mass flywheels are more responsive than dual mass designs since there is no cushioning effect on the drive train like the dual-mass design. Shifts on these flywheels are noticeably more responsive but they can be harsh at first; especially for drivers used to dual mass designs. This is because the clutch is allowed to engage fully, without dampening, as soon as the pedal is released. This allows the driver to have more control over the way that the clutch engages but it’s up to the driver to make sure that he or she does this smoothly to keep from damaging the drivetrain or jarring passengers.

 

 

 

 

 

Lightened Flywheel

Lightened flywheels are the realm of drivers most dedicated to performance. Bear in mind that they are really not for cars driven on a daily basis. A lightened flywheel produces more responsive shifting and engine RPMs as well as generally improved acceleration throughout the gears. That is because the rotating mass is drastically reduced.

 

Lightened flywheels reduce drivability under most circumstances. Cars with lightened flywheels are more susceptible to stalling in traffic, are much noisier and will probably increase engine vibration, thus reducing engine life. For most drivers, a standard or slightly lightened single-mass flywheel gives the biggest performance benefit without the trouble of a these flywheel types.

Don't do it.... its suicide 

 

 

[techieboy]

And another with beefier clutch (and no balance shafts either, not that you can tell).



Save yourself £250 and don't bother, if you haven't already bought it.

Get some high speed lift off overrun slowing down distances done before and after

You didn't go for the Crome extra shiny option ? Not like you!

Gordon, that photo was taken the other week, Ive had that flywheel fitted for 3 years.

Gordon, that photo was taken the other week, I've had that flywheel fitted 3 or 4 times this year. Corrected Mark

OP, just keep it std. 

 

Safer that way.

I am of course forever the Court Jester. Easy to handle, rev needle spins up and never had issue with it. Massive dirrence to my n/a on standard. Made a very noticeable difference but for me zero difference in difficulty driving.

[Firthy]

For me I found a huge difference in changing gear, the original is stupidly heavy and the syncro's did not appreciate the mass.

 

Barely notice it in traffic.... and as an N/A heel toeing rev matching was so much easier and the engine felt much more alive.

On my NA a lightened fly drives ok, but not too light...

I have one fitted of around 5.8kg, but the TTV ones are more like 4.2kg and that is a bit too light for my personal taste.

 

Each to their own though...

[swisscott]

I have a lightened flywheel and the balancer shafts removed. No driving or stalling issues whatsoever !

 

But it's worth its weight in gold when heel-and-toeing, much faster, much better to adjust the revs.

 

When you're in gear there's NO faster acceleration or less engine braking.

 

When you're in neutral or pulled the clutch there's much faster rev change. 

 

"Engine braking": If you're downchanging without matching revs then the engine has to spool up which takes more energy when there's a heavy mass (flywheel) so the engine seems to slow down harder. -->>

 

But this is not the way to change gear in a sports car
