944S2 Track Car Project - Spa April 2019

[blade7]

Corrected Geometry wishbones are available for about a Grand a pair from the states, also somebody else in the USA a bit cheaper I can't remember who, or make your own. They sit the car's wishbone correctly (Flat) on lowered cars.

R

A lot cheaper to raise the inner pick up point on the cross member....

Really.. How ? there's no space on the subframe to have a raised position using the stock wishbones otherwise the Racers would of done this, hence why they extend the outer wishbone pin

or extend the stub axle stem like I did, but I went one further and used stock 944 later wishbones but with a High quality Rod end screwed into an aluminium bush.....

R

Yes really....

Looks like the self-proclaimed suspension guru fails to understand basic tenets such as what the coefficient of grip is.

As is typical in these sort of conversations, just because you haven’t/can’t do it doesn’t mean it can’t be done.

Excellent, Now we're all really going to learn something !

Type away and you know the drill (lots of pictures please...) []

Hey I'd stop bit so negative if I was you, Karma has a habit of producing the goods....Hows the rebuild going!

Perhaps you'll just have to take my word for it....

As you will have read, I have had some tuition from Mike Wilds - at Donington. He's also driven my car. I reserve the right to choose who to learn from though...

 

[Eldavo]

Rebuild is going well, I’ve refrained from drilling 5000 holes in anything structural and managed not to crow on about something irrelevant that my dad’s brother‘s mate did in 1986 - you could learn a thing or two.

I see “new year, new you” has passed you by and I can only hope that someone only put 50p in your internet meter and it runs out again soon.

I believe that over in the 924 forum there’s a village looking for its idiot, once again you disrupt the fabric of this forum with your sanctimonious twaddle and take the approach that saying as much as possible is better than being correct.

Seeing as you’re always so eager to learn then I can provide some unique insight into both why you’re a few seconds a lap slower and also why you’ve never experienced a loss of rear end grip in a corner . . . You need to drive faster!

I hope that your racing career is mercifully short and that my love of Shadenfreude is met x

Very Unlikely! Next you'll be telling me you can spin the wheels in 4th at 100mph !

I could of bet my 2 houses on the fact you'd not be illustrating anything !

If you claim, then don't tell it goes down as hot air........

[blade7]

I've got a picture to prove it.....

It's known as a "Circle" for some people, but those that have ventured further been on courses, (25 Years ago!)

passed with colours and won races understand more on this.

In reality as data logging illustrates there are differences and the edge of whats termed the circle is not an even radius round shape at all but more like a diamond shape.

The forces available for lateral acceleration & Braking are not the same as Cornering, as there is more traction available for cornering.

And there isn't a linear relationship between speed and cornering force or the slip angles, then there's the Yaw but i think this is getting too deep!

Please stop - all of you []

I bet you my twenteen houses most of this gets deleted

OK back on topic... and back from Spa..

The day started dry, then greasy, wet, dry, wet then drying up again, so quite challenging... It's a fast circuit & there's plenty to hit at Spa.

It's a stunning circuit, and well worth a visit.

190 track miles, 1220 miles on the trip, car now tucked away.

(Pics are on photobucket - hope you can see them)

Very Easy to make a mess of it then in those changing conditions well done for bringing back with all the paint in tact!

Same set of Tyres on all day? and of so what flavour and sizes...

Eau Rouge entry 3rd gear ? and how long ae you in 5th down the straight, unless you've changed your box the gearing should be

the 3.375? Only I'm using a 3.889 and wonder if that straight is too long for it, although in reality is it that long?

4th into eau rouge, exit radillon at an indicated 95-100 onto the straight.

Change into 5th at 120 ish about 1/3 up kemmel straight. It's uphill, 5th only really maintains the speed. Spa certainly suits more powerful cars.

Tyres are AD08R, 225/45/17 all round. Car was driven there & back on them.

Nice pics Ed. I particularly like the first one []

Ok then I may max out in 5th with my higher gear final drive, Max Speed at Donington and Silverstone was 110mph in 5th with only about 1000rpm to go.

The Yoko's were probably as good as you get for Driving to and back, and the tracks dry and wet conditions.........

Stiff sidewall, medium hard compound so they won't melt even if it was very hot, and those Sipes will evacuate standing water better than a semi slick like a Dunlop Direzza or R888 etc...

Excellent - looks like a lot of fun, a circuit I would love to drive one day.

I treated myself to a set of the dual lens GTP headlights, (had been thinking about making something similar for years - decided I am not getting around to it so indulged) not tried fitting them yet but very impressed with the packaging, the instructions and how they look on the bench.

Not the best picture but I haven't unwrapped them yet - cat approves!
