no i have tried cannot make sense of paste the link? picture into a post?i am trying to upload from my photos
MrD i'm no expert driving expert but my car certainly doesn't feel like it significantly understeers. I expect Porsche sets the cars up to be controllable in the hands of the majority and then those who want something more extreme or know exactly what they want, will have to tweak it. So I don't feel I have an understeer problem. That said, doesn't understeer make a car more controllable and forgiving at the limit? If you have understeer, you can apply some more turn in whilst on the gas with less risk of overdoing it into oversteer. If the car is set up to turn in sharply, then for the average Joe, if he overdoes it on a corner and loses some rear traction, isn't he more likely to oversteer off the road or into a spin? As I say, those who know exactly what set-up they want can tweak it, but it wouldn't surprise me if Porsche have achieved exactly what they set out to by not making the car too unforgiving for the average pilot and more progressively controllable at the limit. Last week the car got pushed into oversteer. Yes it was damp but something else must've been on the road I think. I wasn't going that fast but I applied some power as I went through a green light and turned onto adjoining road, so maybe I was going faster than I thought as these cars carry a fair bit of speed through some tight corners. The back end got loose and I was heading for the curb. The when the traction regained, the car snapped straight and I was saved. It was a horrible moment though. My said I applied some opposite lock (yes he knows what he's talking about and beats me on GT5 and knows how to drift on Need for Speed!). I guess I did it automatically and don't recall that myself and hence the car pulled straight when the back wheels got a bite again, but I wouldn't want my car with a reduced tendency to understeer as that occurence may happen more often. Each to their own of course!
If you start to have under steer, and you apply more turn in, you will get more under steer. If you apply more gas you will get even more under steer. You grip has gone so doing either of the above makes it worse. All about slip angles. I hate the feeling, you pray you get grip, the only thing you can do is let off which tucks the noise back in but can cause life off over steer, or wind the steering back a bit. with oversteer at least you can do some thing about it. Not that my car over steers, it just much better balanced now and does not push like it did before. The LSD don,t help, pushing more , but does help in the over steer department giving you rear traction. Look at your oem cambers, the rear is set quite high vs the front, so mid corner you getting the full patch on the rear tyre while the front is rolling off the shoulders. I was wearing my outer edge on the front and not even using all the tyre on the rear. Which is a crazy oem set up. Now all I want to do is go out and drive, but my gf thinks I am mad wanting to go out at 10pm for a drive to know where lol. My car is night and day running -1.2 over oem for the better by a long way. Do the chalk test on you tyres and see how much or how little of the tyre you are using. I see wannabe with loads of camber, but don't drive fast enough to use it, so pointless, it's quite funny on a track day. Not that I am a pro race driver or any thing, I feel quite slow these days, must be getting old.ORIGINAL: flat6MrD i'm no expert driving expert but my car certainly doesn't feel like it significantly understeers.

Just been out for a blast with some guys on PH some stunning cars .Dodge Viper.Ferrari 358 and 460 Lambo. Boxster. 964 . Skoda VRS Lotus Elese and various hot hatch's ,Went up the old military road around Loch lomand . Stopped in a lay by looking down on Faslane submarine base stunning road and views sorry no pics .And hood down all the way 100mls Brian
-1.2 is nothing any way and you would still wish for a lot more on a track. The guys in the states run -1.8 even on the road and -2+ on track. -1.2 is the max these cars can do on oem LCA and top mounts. But I am very happy with the outcome so will NOT be fitting LCA,s ( on the r at least) The Spyder might need LCA once I have fitted R spec tyres though. But I hope I can drive round it without having to buy them. Having the front with no toe in just stops the tyres fighting you wanting to turn and gives you more feel, make the car feel more alive. Again on track most have slight toe out, but on the road that is not nice.
I hear you MrD. Most manufacturers tend to engineer in a tendency to understeer because at the limit, it's a fairly stable state for the car to be in. If you lift off, with the reduced speed you can get the fronts to re-bite and then can turn in again. Or, you can straighten the fronts a bit into the direction of the understeer to alleviate their struggle and when they gain grip, you can have another go or then brake. After braking, you can have another go. (Sorry I didn't mean you can simply turn in more without doing something else first for the fronts - that'd exacerbate their lack of lateral grip!) Not saying those are the quickest way around a corner, but it's about when you've already overcooked it. The natural tendencies of a driver are more likely to correct understeer and more likely to make an oversteer worse. Also, when oversteer happens it's less progressive and most drivers if they don't know what they're doing will not react quick enough and with the right technique to catch it. The early Honda S2000 was prone to oversteer and putting itself into a ditch. Honda had to revise it by softening the rear suspension, stiffening the front and fitting wider tyres, to make the car more progressive at the limit. This all went against what they were originally trying to achieve for the enthusiast who knew how to exploit it, but it was too unstable when not handled with care. BUT I acknowledge that your car is NOT oversteery, so i'm glad we've cleared that up! I will have more of a think about your geo changes[

]Good to hear you're getting out and about in it Brian. I got my car back yesterday after getting the wind deflector clips replaced. Not that it stopped me getting the roof off, but it's just in time for the good weather predicted this weekend. Also got 4 new tyres begging to convince me that they were worth it[
] I bet in amongst all that metal you still had a conversation with someone about your Spyder[]
flat6 you could have done Mr D tyre inspection and got an idea on how your geo currently set is wearing and gripping or am I misreading all the data above Where you not tempted to have tracking checked whilst fitting four new boots[&o]ORIGINAL: flat6 got 4 new tyres begging to convince me that they were worth it[
It's a good question. I didn't think of it but they tyres wore so evenly and I took them down to 2.x mm across the whole of each of the tyres. I really couldn't ask for more. Nothing was lost due to uneven wear and I got my money's worth I think. Take a look at this Michelin tyre (no it's not my car). The out edge tread is so shallow even when new. But at the end of the life of the tyre, it still even has some tread in that outer section. They use a varied rubber compound across the tyre.ORIGINAL: daro911flat6 you could have done Mr D tyre inspection and got an idea on how your geo currently set is wearing and gripping or am I misreading all the data above Where you not tempted to have tracking checked whilst fitting four new boots[&o]ORIGINAL: flat6 got 4 new tyres begging to convince me that they were worth it[
next track day is 11th June but as all tests seem to be saying 2 to 3 seconds a lap faster than the best road tyres, they should feel amazing. (also very light) sweet . I see 2 Spyder owners have bought P zero again (what a mistaka to maka) Pilot Super Sports are the only all year tyre to own imo. If you really need N spec Pilot Sports are the next best.
Dunlop SportMaxx Race The Dunlop SportMaxx Race is a Extreme Performance Summer tyre designed for Passenger Cars. The Dunlop Sport Maxx Race has been specially designed to help some of the world's fastest cars perform on some of the world's most challenging race tracks, while ensuring they are able to deliver their drivers back home without the need to change tyres. The new tyre is developed to fit the needs of some of the most high-performance cars on the road today including the Mercedes SLS and C63 AMG Black Series, Audi's TT RS and R8, the Porsche 911 GT3 and the BMW M5. "Throughout its long history, Dunlop has always had a racing tyre for the track enthusiast and today we are putting ourselves back in pole-position in this category with the introduction of the Sport Maxx Race" explains Sanjay Khanna, Managing Director, Dunlop Brand. "With thousands of hours of development work behind us, we are confident that we have taken into account even the smallest details to ensure we deliver a tyre that can transfer the car's power to the road with maximum impact". Dunlop's Sport Maxx Race delivers a solid grip on dry road surfaces, supported by a motorsport derived compound which delivers a blend of race-proven polymer and a traction enhancing plastifier, leading to higher compound adaptability to road surface. It further provides drivers with a strong confidence on wet road surfaces, thanks to four inner circumferential grooves for better water drainage. Helping to ensure that drivers keep their vehicles well-balanced in corners, Dunlop's Sport Maxx Race builds on its asymmetric pattern design on a massive outer shoulder block, generating higher cornering grip on the track. Further improvements in cornering grip are delivered thanks to high angle ribs, ensuring increased lateral stiffness. Superior high speed stability is driven by a hybrid overlay featuring Aramid, a high strength and heat resistant synthetic fiber. Aramid is also used in aerospace and for bullet proof vests. "Our new Sport Maxx Race tyres are the perfect choice for the serious sportscar driver that wants to take his car to and on the track. Delivering some of the best on-track performances for a tyre that is also roadworthy was a key requirement for Dunlop when it first started developing the Sport Maxx Race and we have delivered on this" says Sanjay Khanna, Managing Director, Dunlop Brand.
