Jap Devil Posted September 8, 2006 Report Share Posted September 8, 2006 First lap after the parade lap, I was second with an ST24 Mondeo in front of me......I wellied it past him on the Pits Straight @ 120mph but ended up with a bad line into Copse Corner Result.... Track was wet on the outside of the corner, I felt the back end throw a wobbly, overcorrected and then went spinning off onto the run off area which was fortunately tarmac rather than grass of gravel And on the second lap....I did exactly the same thing again Dave Ellen took the vid Mike's Spin Quote Link to comment Share on other sites More sharing options...
Bazza Posted September 8, 2006 Report Share Posted September 8, 2006 i wouldnt feel too bad zee from LOC and janey both span out at silverstone mind you they only did it the one time ! Quote Link to comment Share on other sites More sharing options...
Tony Posted September 8, 2006 Report Share Posted September 8, 2006 Thing is do you feel you know why it happened...... we know the car is undergoing heavy modifications, this takes time to learn on the track.. And the conditions invited over-steer. Corner 'in' after the straight is the hardest to handle for anyone. Quote Link to comment Share on other sites More sharing options...

scorps Posted September 9, 2006 Report Share Posted September 9, 2006 If you sign up to do a t/day then you must expect the unexpected,if you spin off and crash your car then sobeit...its a learning curve I crashed twice at Brands on my R1 at paddoc Hill,repaired it then it was on to the next t/day Quote Link to comment Share on other sites More sharing options...
nick the greek Posted September 9, 2006 Report Share Posted September 9, 2006 You think you'd learn after your first spin there mike! It had dried out a lot by the time I got on track at lunchtime, and mine was completly my fault! I thought i'd try and get a bit of drift practice whilst out on the track Needless to say, I need more practise Quote Link to comment Share on other sites More sharing options...
Paul TVR Posted September 29, 2006 Report Share Posted September 29, 2006 I've done a few track days and the best way is to start off slow and build up to a good lap, take an instructor out with you at every new track you visit. I've spun at a few in the TVR and very nearly made a big mess of it at Castle Combe due to a Cossie boiling over and dumping its coolant midway through one of the back faster corners.

I've spun at a few in the TVR and very nearly made a big mess of it at Castle Combe due to a Cossie boiling over and dumping its coolant midway through one of the back faster corners. I am desperate to ask, what set-up do you have for the car Ok I had the car set up by a company called Topcats racing who set up a lot of race Tuscan's etc. They use the old fashioned method of string boxing the car but with very good results and also corner weighted as well. The car is running Redline shocks with Nitron springs, but I can't remember the spring rates, I have a feeling they are 325 and 400 lb though. Front Camber 1.75 toe in 5 tyre pressure 22 ride height 140mm shock set 15 clicks from fully hard Rear camber 1 Toe in 2 tyre pressure 22 ride height 200mm shock set 15 clicks from hard weight 2395 Lbs 1088 Kilo wet weight with 3/4 tank fuel. The shocks were adjusted at Brands Hatch track day to slightly stiffer at the rear. Topcats added extra camber to help with the understeer and also altered the rear alignment as the rear Toe was all on one wheel. they added extra toe as they old set up would grip very well but when it broke away was very hard to catch, the new set up gives less overall grip but a much more progressive feel. the only down side to the set up is the large amount of camber causes tram lining or badly rutted roads but it is worth it as I can throw it into a corner and such greater speeds now. I don't pertend to understand much about geometry so if anything I said there is wrong I must have got it mixed up Quote Link to comment Share on other sites More sharing options...

Me being a crafty devil wonders if you also have the data for the KPI and Castor positions... this would complete the overall image and not an unreasonable request ....

I don't have the caster or KPI on my spec sheet. this is a hand written sheet due to using the oldie ways of string boxing the car. no new fangeldangle laser equipment in the workshop. although the corner weights and linking the the palm was quite nifty. Guess they use what works for them. Quote Link to comment Share on other sites More sharing options...

Although for anyone contemplating using TVR on the track we do really need to establish a steady footprint! Well as said with that set up I couldn't believe how it handled at Brands, they use the same method with their Tuscan race car and having seen that put in a very impressive run at a 12 hour race there a month before I was quite confident they knew what they were doing. http://www.topcatsracing.com/ are they people who did the work. Once the track work resumes I'll look into fine tuning if it needs it, at the moment I think the car is much more capable than I am though lol Not sure if it helps but I have a few pictures of it on the track, not sure if I can add them here though?

Tony Posted November 24, 2006 Report Share Posted November 24, 2006 Then a few safe 'off's' are commendable with a new drive.... no shame in that..If you stay on the track to long then you are not driving hard enough in my opinion. Quote Link to comment Share on other sites More sharing options...
jon Posted November 29, 2006 Report Share Posted November 29, 2006 Exactly Tony, i span 3 times on silverstone national, though i was never stupid enough to spin at copse I span trying to drift round luffield on totally shot rears a few times then once on maggots corner the next lap as the rears had literally gone to jelly. I came in a lap later after a slow COOLINGDOWN lap and they read nearly 100c, too hot to touch! Quote Link to comment Share on other sites More sharing options...

The Indexing/ Geometry and tyre temperatures should make for interesting analysis (albeit secrete) ready for next years season... Quote Link to comment Share on other sites More sharing options...
