I think it is:

Leda suspension
upgraded sway bars and sway bar links
bumpsteer mod
AP 6-Pot kit and brake support bracket
18" OZ P1 wheels with Pirelli P Zero competition (225-35-18)

....interesting to read what you think about it?

the 'ultimate' setup will probably vary a bit, depending on the track.

surely slicks would figure on the list - made a big difference at bedford

IWatkins

Leda not even close enough to 'ultimate', and surely it would be 19's, slicks and some wild camber

Cheers

Certainly can help.

But before you junk the stuff you have just bought, mail me the damper and spring rates and details of your geometry.

Craig...

Spot on mate. Its what I tell everyone looking for big power. It takes a well sorted Scoob to beat a Fiesta Credit Challenge car around Donno. They haven't got much over 100bhp, but handle and stop like you wouldn't believe.

dingy

Pete, I don't think My GRP IV Tarmac Billies would fit your car....

I have tried, SPAX, LEDA and Bilstein on my car.

Bilstein are by far the superior for my car.

Pete Croney

Sean... In that case, they wouldn't fit Ric's car either

You should have been at Siverstone on Saturday, "Shed Heaven" mate

They were running an Escort championship. Great to watch these things going around the rallysprint circuit. Tail out action the whole way around. Really felt for the guy that seriously rolled coming into the start/finish bend. Not a straight panel on it.

Mark Brown

What Bilsteins are the best??

I read that there a few different types??

What about the Bilstein Coil Overs when are they due??

ric

Kryten,
Pirelli P Zero competition tires are slicks (Intermediates).

Ian,
what is close enough to ultimate? I thought Leda was absolutely the best money can buy? 19" slicks....oh man, that could be expensive.....

Kos,
The bumpsteer mod is from Powerstation and is well known to remove the understeer of the Scooby.

Dave T-S

The Pirelli P Zero C is a treaded tyre, not a slick - (and a slick is not an intermediate....).

See:

dingy

I would have said DMS or Bilstein would have been a better choice than Leda.

But its how the car feels to you, i wouldn't change my bilsteins for leda at all....

Hyperex

Why ain't anyone discassing about the Camber degree, Toe setting, ride height, tire pressure, spring rates etc... I thought these are "setup", which are supposed to be the most important part.

Just fitted Leda - so it's all been done

Pete Croney

The ultimate track suspension (whether it was built by Leda or anyone else) would be almost undriveable on the road.

My RA has BTCC spec (lightweight short tubes, high bump, low rebound rates) Leda's using 700lb springs. It is just staggering on the track (sorry Dingy, wouldn't swap it for your Bilsteins ) but it is far too compromised for fast road use.

And with the geometry and ride heights correctly set for the suspension location points and roll centre geometry of the car, you don't need to shim the rack (bumpsteer).

I've just got some 18" Michelin Pilot Sport Cup tyres to try. These are C rated, road legal, cut slicks and are meant to be 2 seconds quicker around Snetterton (same car) than a Pzero C, with better wear rates. We shall see

For the best track set up, You'll never beat a full slick.

Pete Croney

Oh... and the Impreza running the Leda race set up in the Irish race series is winning the lot.

We've just supplied his main rival now as well

ric

Dave T-S,
sorry I am not the absolute specialist in tires. But the Pirelli Zero C gave me almost the grip level of a slick I think.

Pete,
my Scoob has now Koni adjustable dampers (yellow) and Apex lowering springs. The weekend I drove at a so called "slalom race" in Switzerland. They built a good track on an airport with "pylones". I was very unhappy with my setup, lots of body roll and understeer. Now I am looking for a setup, that gives me the ability to corner like mad. Could you provide me with such a setup? I use the car on track, at "slalom races" and on the road. But my aim is performance on the track!

greetings and thanks for any information
ric

I think the scary thing is, you apply those principles to "cheap" hot hatches and you have cars which will be substantially quicker round a track than a Scoob/Cossie with road Ledas etc etc.

I'm confused
What is 'bumpsteer'??

Im looking for a decent set up for track days / fast roads for my MY01 WRX

Can someone explain

a) what is the advantage of having externally mounted gas reservoirs on the suspension is. Its offered by most suppliers. Is it overkill for my sort of driving?

b) Do you adjust the suspension for track/road depending on what you are doing - or does one setting work for all

c) Will i go quicker with decent suspension or more power??? Which should be sorted first

Jza

Neither - get the brakes done! The ability to stop consistently, lap after lap will give you more confidence to keep pushing and will also have a staggering effect on your performance.

Lambo

Mr Croney, how come you have managed to get hold of some Michelin Sport Cups, I thought they were only supplying these to the Michelin Porsche Cup/Classic championships at the moment.
I do agree with you r findings though, I run a Porsche 911 in the Classic championship and was 2 seconds quicker this year at Silverstone than last year on the Pirelli P-zero C's.
Have a look at the site

Dave T-S

Oi - Sir Pete - trying to outdo me.....I took it to mean pure road cars

jza
a) externally mounted reservoirs are for competition use. They remove the fluid from the heat source. A damper produces a tremendous amount of heat when it is working hard.

b) Leda's are 24 point adjustable. Mine are set at something like 3 front and 6 rear for the road. For the track, you crank 'em up about 15 points (Pete's the expert...).

c)Brakes, suspension, power - in that order.

Pete's car gives away power to, say, a P1 but carries far more speed into, and through, the corners.....or at least he did when he went past me at speed at Bedford

Cheers Dave. Are our standard 4 pots not really up to the job? I just thought id be better off with suspension 1st (for the road use) and do the brakes afterwoods if i need them for the track.

One point - i thought that adding serious brakes without modding the suspension is bad news - lots of front dive = loss of grip at back = spinning top

Is that right?

Thanks for the info!

Jza

Pete Croney

a) As Dave has said, they are overkill and we don't recommend them for road use. The gas pressurises the damping oil to 175psi, the purpose being to raise its boiling point. For fast road and track use, you would never boil it anyway, but this pressure does put a lot more loading on the seals and these need more frequent maintence. Leda circumvent the problem of fluid temps in two other ways... firstly the damper contains 150% of the target fluid volume, secondly the oil in circulated unidirectionally, irrespective of whether the piston is rising or falling, and the damping oil is always drawn from the bottom of the reservoir. This ensures the valves always work on fresh oil and the temperature is kept stable. Leda use Silkolene damper oil, as do Proflex and Ohlins.

b) You adjust it to suit the conditions. Gentle drive, mad cross country blast, smooth dry wet, wet track etc. It takes less than 1 minute to adjust all four corners. You can also adjust the ride height, for a track day, but most people leave this at the factory setting.

c) I strongly agree with brakes and suspension first. If you are fitting really big brakes (eg AP 6 pots) and are using slicks, you may want to fit suspension at the same time. This is because you can apply so much braking that you will be on the front bump stops, with the rear wheels totally unloaded, with the standard suspension. Good suspension will hold the car flatter, giving less likelyhood of locking a rear (or activating the abs, which then kills the braking power) and making the car more settled as you come off the brakes and turn in.

Lambo...

Its not what you know and its not who you know, but what you know about who you know

They look the absolute nuts, should get them on in the next couple of days. Have heard great things and your times back this up. Good site, with great pics, by the way

Lambo

The Pilots do look great fitted, they have a thick sidewall which sticks out past the rims, looks mean and also saves your rims if you scrape a curb / bash wheels with another racer. Not sure how long they will last on the road though. On the race cars they will do two qualifying sessions and two races before starting to look shabby. I have also been told that they are very easy to flat spot so no handbrake turns

ric

Pete,
I will email you my damper and spring rates, but I don't know them, so will ask the dealer that sold me the parts. But anyway, looks like I will be buying Leda B, I like the idea of adjusting all the settings in 1 minute .
What equipment is used to fit the Leda B, I certainly cannot drive to UK just to have it fitted. You already wrote that but is it really true that after fitting a Leda suspension I don't have to do the bumpsteer mod?

Jza,
I agree with Dave T-S and Pete, do brakes+suspension then go for more power. There was a Scooby with more than 300bhp at the race here in Switzerland. My car is a MY98 with exhaust system (thanks to Pete ) and some modifications to the intake. So is around 220bhp. But I was a lot faster than this car, because of my suspension. There was one Scooby with OEM engine and OEM exhaust, but BIG brakes, slicks and suspension (adjustable, don't know what suspension), he beat them all!

I think the Scoob (UK) has enough power. Sort out brakes and suspension, then if you really want fit an exhaust system or/and PPP and it really flies!

Lambo

Are these like yours?

Ric

I can send all the installation/geometry info with them and any good workshop can fit them, with this info.

ian_sadler

Hi Pete,

Now you have had the BTCC mods done on the MY01 that makes it undriveable on normal roads what do you drive to work?
