Firstly I don't need to read books to learn about driving, I race and I build race cars, I know that a perfectly built and setup chassis system has major benifits but we're not talking about anything like that, we're talking about a cheap set of "coilovers" and swaybars. I already have my degree in chassis dynamics and I know what's usefull and what's not. Going back to the original argument fitting a good set of brakes all round will have more benifit than making a half arsed attempt at improving the suspension. If you did a brilliant job on the suspension which takes a lot of time, testing, money and effort you will have better lap time gains than the brakes will give you however Lele is not planning on making this investment, he just want's to spend some money improving his track experience. If you looked at his suspension plans and knew anything about building a track car you would realise that he's wasting his time and money. Not only that he has no plans to do any setup or adjustments to the suspension once he's fitted it which again defeats the purpose of fitting it in the first place, geometry and settings are what makes it work. You can actualy reduce the cars handling abilities if you don't do these things properly. Under these circumstances it's better to go with something you can just bolt on and have instant improvements from.
You've spent most of your time on this thread telling everyone that stock pads are perfectly suitable for track use as long as you don't use them too much, but failed to emphasise the fact that your using street pads in a full aftermarket Stoptech Big Brake Kit and I'm sure you also use braided lines, full race brake fluid, additional cooling etc. Lele does not have any of these things, his brakes are 100% standard. Trying to relate the two is dangerous, I sometimes use street/fast road pads on track too but I also use a BBK. Completely standard discs, calipers' pads' hoses and fluid on a race track is a recipe for disaster unless as discussed earlier the driver brakes extremely early and lightly for each corner but that kind of defeats the purpose of being on a race track. As you say, track pads will allow you to reach higher heat thresholds which basically means you can use them more aggressively before they cook themselves which means you can brake deeper and save lap time. Great! What is wrong with that?
I agree tyres are very important, earlier I said this
"Tyres are however the most important aspect of all. Everything you do is transferred to the road via those tyres. If they are useless then nothing else can work to the best of its ability. With tyres though you have to make a proper job of setting up the geometry and keeping an eye on tyre pressures. If you don't its another complete waste of time and money and you will miss out on all that potential."
Again I refer you to the fact that Lele has no plans at all to do any setup or adjustments to the car neither has he made any provisions to make sure that the original geometry settings ( as terrible as they may be ) are kept in check. The gains will therefore be minimal.
I'm not trying to be awkward here, I'm just trying to help out a guy who's planning to flush a lot of money down the drain. Have a word with Memo, I gave him advise regarding what parts would make the best improvement on track on a limited budget. In the end I sent him £450 worth of parts but most importantly a complete geometry setup for his car. In his words the car was completely transformed and that was backed up with lap times, all that was without a crap set of "coilovers" in sight.
That's the benifit of having read all the books years ago, getting my engineering degrees, building cars and knowing what I'm talking about.
