I've seen a thread elsewhe

I've seen a thread elsewhere where there was a discussion reagrding a Daytona clutch fitting a 308QV, and one suggestion was that there were many better (more modern) solutions that would be infinitely better. Could anyone suggest a solution that would include a more responsive clutch suitable for road and some track use.

Thanks

Hi Simon,

yes I make that suggestion when ever this subject comes up. The 4V Pressure Plate was a redesign of the early Daytona/308 pressure plate that moved the fulcrum point, thus increasing 'clamping force' while at the same time decreasing peddle effort. So to date the best stock clutch remains the 4V unit.

One of the things never talked about or overlooked is that sometime in the very late 80's/early 90's asbestos was banned from use in brake pads & clutches. When this happened a vegetable fiber, glue, metalic compound came into use that proved to be inferior to the previous asbestos compounds by several fold. These days however science has caught back up to the forces & laws of physics and most new clutch discs & brakes are far better at handiling both "the Heat" and the friction needed for longer life.

Hi JRV,

Have you got any experience or knowledge with using a Kevlar type clutch, as someone suggested to me? This sounds like a reliable modern solution to me.

We used Kevlar clutches on our

We used Kevlar clutches on our FF2000 cars, and I know Chris Parr (f-chat) had a carbon clutch on his F-40 for a short while.

The clutch will grab VERY quickly, which is great for track use, but very difficult to deal with on the street. Chris removed his after about 1-month b/c it was just to much of a pain to deal with on the street and I understand why.

There is very little play and it's really an ON or OFF type of thing. Very little slippage, which as I mentioned is great on the track, but a pain on the street.

I don't know of any Kevlar clutches specifically for the 308QV, but you may not like the grabbiness (is that a word?) of it after you get it in.

Hi!

I use my 308QV for track mostly and some light racing, so I'm looking for a solution that offers little slippage.

I've spoken with a guy named Butch Hooper in Italian Autos (in the US) and he says that he can provide a kevlar clutch for $800.

"We have a company that rebuilds clutches for us for performance. The Kelvar rebuilds are $800 for the clutch and pressure plate and it takes ~ 7-10 days from the time I get your core (or $150 core charge). According to the company, it increases both the life and holding power at least 50%. My customers have been pleased with the results."

So that $950 with the core and $95 for shipping to the UK. What do you guys think of this?

Thanks!

Hi,

Maybe you can contact some of the performance clutch makers and get their direct input and advice.

These are just two I've used in the past with good results.

I sent my 348 Twin Turbo clutc

I sent my 348 Twin Turbo clutch pack to Norwoods and 10 days later he (James Patterson), sent me back a beautiful kevlar unit. It wasn't overly expensive, (comparitively), and can hold all the HP I make. It engages nicely and I can recommend it. Just give James, (or Mike), a call- he knows what you need. Best of luck.

Hi Jeff,

welcome aboard.

Hi Jeff,

welcome aboard.

Are they making their own clutches or are they just middle men on the deal?

The reason I ask is that several real clutch companies will deal directly with the end user which tends to keep the cost down. And I could have easily stuffed myself in the middle if I was that kinda guy...but truly passing along the sources and the savings helps out guys more imo.

Hi!

Can someone please confirm that there is no difference between an UK model 308QV clutch and a US model? I'm speaking to clutchmasters - who have some pretty nice solutions - and they asked the question. I assume there isn't ...
