348 Quantum Racing suspension kit - update

Finally got around to installing the Quantum Racing suspension kit. It comprises of four adjustable dampers and 4 springs.

The items are a lot lighter than stock units and also more modern. Andyhls has had them in his 348 for a while now and he swears by them. I've only driven on the road so far so haven't had the chance to exploit them. Hopefully will be doing a trackday in 2 weeks so will check them out then.

It's on the softest setting at the moment (I live in london) and it is stiffer than standard. Not as stiff as some sport springs I tried a few years ago. It's livable and not that bad to be honest. I was worried that it would be undrivable in town and give me a bad back.

The ride height is a little higher than I would like and I may lower it. Still have high speed stability problems so I'm thinking now it's either crappy steering rack, bad wheels or just bad aerodynamics. More investigation needed on that.

So... cars's had cambelt change/service from my good friends at QV London and I'm now going to start driving it a bit more. Last year I think I drive it 10 times.

Will post pics up when I take some.

 

Just to add....

When it was serviced, I asked them to check the clutch.

I've had the car for 6 years and 20,000 miles now and never changed it. I have no idea when it was last changed either.

It's been driven in town a lot, in heavy traffic a lot, revved a lot, thrashed a bit and there's still lots of meat on the clutch. Very impressed with that.

Just need to get that ****ing Le Mans engine in it now!!!!!

 

Ahhh... can't remember. I think the fronts were 400. See pic below. Rears, I can't remember at all. They were supplied by quantum.

When you coming over to take them out?

Ask for Patrick

There's no part number as I recall. Just ask about the 348 suspension kit I purcahsed.

Here's a couple of pics.

The kit is just 4 dampers and 4 springs. The other bits in the pictures have nothing to do with it. I also got 8 bump stops as well which are not pictured

Just washed the 348 this morning and I was having a look at the ride height. Looks too high and also too level as I belive it's supposed to be lower at the front.

It will be going off to a main dealer for them to sort it out in the next few weeks.

 

No. If the LM engine ever gets fitted, we'll use the TC on the Motec.

 

Sure Patrick, go ahead.

 

Finally managed to drive the 348 properly for the first time last night.

Have only driven it a few times this year with long gaps in between. My friend Adz came to my house and we convoyed to Central London with his Ferrari 430.

I had forgotten the power of the 348 and 15 minutes into the drive when everything was warmed up, I was like wow!!!

30 minutes into the drive and I shouted to Adz in the walkie talkie "This car feels f***** incredible it's like a go kart".

Took it onto central London where the roads can be quite bad and drove it around with other Ferrari's and a Gallardo Superleggera and the suspension/handling feels so much better than the old one. I've got it on the softest setting at the moment and I'll stiffen it up in the next few days.

Haven't tried the car at high speed yet but up to 90 it feels good.

Think I'll go for another drive later.

 

Installed the clicker knobs on the dampers so I can adjust the stiffness.

Turned them all the way to hard and the cars ride is a lot harsher, but boy... does it feel good to drive.

 

Only time I have to compare against is Silverstone and I'm not doing that again until April. Plus I had the suspension settings all changed, so it won't really be an accurate tests.

On the softest setting it's not as harsh as I thought it would be.

However, in my opinion the best upgrade on a 348/355 are AP Racing brakes. That would be at the top of my list.
