Spoke to James @ JBS last night. Told him I was over the moon with the furbys performance since the REVO installation

Main problem now that was noticed 2 weeks ago at Ty Croes, is the fact that is VERY difficult to get all that power onto the tarmac without huge amounts of wheelspin. Tried playing with the traction control button whilst going into the hairpin but very time consuming when you are trying to concentrate with already full hands.

Didn't seem to make much difference anyway.

Coming out of the hairpin in 2nd and then 3rd the wheels just spin away, hence valuable seconds are lost.

Apart from obvoius suspension mods that will help keep the 'light' wheel down a bit more, it was suggested that an LSD would prove to be a big advantage.

Therefore I'd like to know if anyone in here has had one fitted to a Fabia or an Octavia for that matter,and the resulting traction improvements?

Any problems with steer torque? Any other problems or things to be aware of p'raps...apart from the cost...

Whats it stand for? :confused: Sounds very exciting, from the price tag alone. :eek:

Being used to mine then driving Paul's at Anglesey I found exactly the same out of that hairpin, was bloody frustrating at first..... adapted my driving style to open the throttle as the wheel straightened up and it helped, but bear in mind there is a surface change there and there simply isn't as much grip till you are out onto the main straight.

Not really any help, I know

If there's wheelspin, would the LSD help or would grippier tyres be of better use?

Limited Slip Differential

Limited slip differential Jase.

Yes Ian..found that out on my very last run on the Sunday...less heavy boot = less wheel spin ='d fastest time ever for me. Shame it took all weekend for my brain :confused: to finally work that one out!

I'd like to think that it would be even quicker out of the corners..especially the hairpin with an LSD though.

Sadly that won't matter in 12 months, 'cus the hairpin will be gone. :(

Well, even with hot slicks you'll struggle at that particular place.... and if you do get good traction, well, that was where a certain gearbox imploded..

Am slightly worried that the "new" anglesey won't be as good. It will be a faster circuit certainly, but the old circuit is a great leveller of performance, the new one looks to be more of a power circuit.....

Time will tell.... :(

I'm sure it would help, but I think for half that money you could get uprated springs and dampers, strut braces and an anti-roll bar which would probably gain you more benfits overall?

Chris

..or a set of slicks

John, I do believe that includes installation...8 hours of labour! Big Job!

Ian, I was assured that the new circuit would be just as good if not even better. However they would say that wouldn't they? Really don't want to see it moving away from a technical to out and out power circuit.

As much as the hairpin is a total bitch to master..and I still find it tricky after probably 200+ laps over the last 6 yrs, it's a truly GREAT section of track that needed to be kept IMHO.

Stop it! You're making me look forward to e/o November even more now!

Thanks for LSD definition.

After owning the Integra Type R for years - i vowed never to drive another car without LSD.

The grip is phenomenal - slight bit of understeer - plant the accelerator, more grip ensues, and the car pulls tighter. It's certainly an experience.

What sort of LSD you looking at? Best for all round use is probably 1.5 way.

And for

Quaife list 2 ATB differentials for the Octavia at

525 + 8 hours... is about a grand once the tax man has had his slice.

CJ I'd be tempted by a LSD aswell matey...get a lot of TS on overtaking if I indicate, but the real benefits are only ever going to be found on track. I'd like to experince one before I parted company with the present one....perhaps a sprint to Sheffield one day

You do alot of sprinting so I'd say it would be worth it to you...not trying to spend you money, but I do think it's one of those if you track it it might be handy.

That hairpin, nay the whole circuit is a masterpiece of thinking...short enough to learn, and sadly now I'll never do enough to master....they should keep the old track and cone it off/alternate..ho hum.

That would be very interesting..a competitive section through the new paddock/car park!

Only problem with fitting an LSD is that you are putting more load on your transmission and the chances of breaking your transmission increases.

At the moment the wheel with the least grip natuarally spins because thats the way a conventional differential works, so naturally reducing forces on your transmission, but preventing you from putting maximum power onto the road because of wheel spin.

Fit an LSD and power is transferred the the wheel with most grip, so you get more power down when you pop one wheel onto the grass or coming out of that tight corner etc., the down side is that potentially all that torque can be fed to the driveshaft with the most grip, something has to give and if its not your wheel with least grip it will be part of your transmission. :(

The cost of fitting an LSD will not end with the cost of the LSD.

Another way of getting more grip is to use competition or softer compound road tyres, Colway tyres manufactuer competion remoulds which are (or at least were) available is a range of pattens and compounds, very cost effective and at a resonable price.

It's just has been spoken about many times.....

The LSD from JBS is a Quaife Automatic Torque Bias Differential (Or ATB for Short).

I'm pretty sure the price (

That's the bit I couldn't remember..ATB..differs in some way from a normal LSD, but don't know the technicalities of it.

Isn't it supposed to put less strain on the transmission or summat?

Wish I was a bit more techno informed..bit like computers really...I'm learning.

Any of your mates had probs Josh?

None.

They love it!

You have a very viable alternative in a Peloquin ATB diff... Quaife may not have any in stock nor be planning on making any for a while for 02J boxes.. Peloquin are available from AutoTechnik with a drive in drive out service on 02J's currently.

Quaife is the more expensive unit..

Peloquin would be my choice these days. (same as Quaife design but comes with everything you need and still is less money than Quaife's rip off price.)

Cj,

Ask James At Jbs To Take You Out In His Octavia. He Has A Quaife Fitted To That. I Went In It A Few Months Ago And Was Impressed. The Car Still Wheel Spins, But Both Wheels Are Spinning Instead Of Just One. Not Surprising Really When You're Trying To Put Over 300 Bhp Through The Front Wheels. The Diff Will Give More Confidence Around The Bends, But You Can Still Get Power Understeer If You're Too Keen With Your Right Foot. Also You Loose The Self Centre Tendency Of The Steering, Meaning Youve Got To Steer The Car Back Straight After A Bend/turn. The Car Will Continue To Turn Otherwise. This Might Not Be Desirable If You Come To Sell The Car On Later. Overall A Top Piece Of Kit, Albeit On The Expensive.

Before Buying A Diff, Try Looking At Fitting A Rear Arb. This Will Transform Your Cars Handling. A Stiff Rear Arb Puts More Weight Onto The Inside Front Wheel During A Turn. If You're Cornering Really Hard You Might Get The Inside Rear Wheel Lifting Slightly. That Weight From The Rear Inside Corner Is Put Over The Front Inside Corner Resulting In Far Less Understeer.

Anyone know if there are any rear ARB's available for the Fabia? I got the impression there weren't and Eibach only made a front one but I'd be interested to hear from someone who knows
