Club member mate who has a 310 has had the even lighter PP flywheel and a new clutch fitted. 
This is what he told me:

"The ultralight flywheel and clutch is £1375.50 + vat fitted.  If you require a replacement clutch slave cylinder then this is either £104.31 + vat for the earlier cars or £140.00 + vat for the later cars."


"The Premier Power Ultra Lightweight Flywheel & Clutch is an entry level upgrade that gives a very noticeable driveability improvement.  It will give the driver a heavier clutch pedal but an increase in throttle response and the improvement in engine braking is very noticeable.  For those interested in improving the performance of their Sigma but that don’t initially want the expense of an engine upgrade, this is the perfect product for you.  It makes driving the car a completely different driving experience.  With the engine being far more responsive, it’s a lot easier to flick through the gears, increasing the sports car feel.  The sprung loaded centre plate also helps to protect the gearbox.
This product can either be fitted to a standard Caterham Sigma engine or a Premier Power modified engine.  Once purchased this clutch is suitable for any of the Premier Power engine upgrades and does not require uprating for any of our upgrades.  A new master cylinder is supplied as part of the kit.  However we do recommend while the engine is out to replace the slave cylinder and release bearing.  Should the old unit fail, there would be an additional labour charge to remove and re-fit a new one "

He had that done plus a cat bypass and is very pleased with it all.

I had a 310r and started with the ultralight flywheel and clutch. I then had the cat in the can exhaust fitted followed by the F160 cams and remap. I was then contemplating adding throttle bodies to take it to F175 but decided that life's too short so opted for the F190.  
In addition to Silverstone, at Motorsport Days Live, I also took it around Bedford Autodrome yesterday to test the new windage tray that Stuart had fitted. Needless to say it worked a treat with hardly any oil in the catch tank.

Compared to the 310r I started with the car is now transformed, it pulls and pulls, I can't believe it's my car and the only thing holding it back is me! 

You know you want to do it so just find a way to make it work. It's worth every penny and the after sales service is second to none.

Hi Chris. How did the F160 spec compare to your start point - 310/152bhp trim? Sounds like you had the posh flywheel fitted before the F160? 

I'm in a 270 and will either covert to OEM 310 or go to Stuart for F160.

The F160 was much sweeter running with more low down torque than the 310. My 310 had 148bhp when I got it and the F160 had 163bhp, although I never experienced that on the road as I had it limited to 155bhp for the speed championship. 

My car started as a 270 and Caterham carried out the 310 upgrade, but kept the standard Ford flywheel, before I bought it so the ultralight flywheel made a huge difference.

I think the ideal starting point is a 270 as Stuart's F160 gives so much more than a 310 and you save money by not having paid more for a 310 in the first place. His cams have more lift than the Caterham 310 cams and he sets the valve clearances correctly.

This is my car converted to F160 before it was restricted.

Uhoh. This is getting dangerous financially. 
 

so I've been quoted £3200 inc vat and labour for the OEM 310 conversion including the CC light weight flywheel and a decat pipe. 
 

F160 plus the ultralight flywheel is the same again including the vat. Worth it? Quick, while the bank manager has his back turned....

It depends what you're after. If you think you'll be happy with 148bhp and the heavier Caterham lightweight flywheel then go for it. However, if you opt for the F160 with the ultralight flywheel you'll not only have over 160bhp and a super responsive engine you'll also have an upgrade path in future should the bank manager turn their back again!  
It's also worth mentioning that Caterham don't fit upgraded valve springs with their 310 cams.
In answer to your question 'is it worth it?', YES definitely but you knew I'd say that!
