Got a better wheater (A little cold 8ºC and sunny, track was clean and very grippy) and took me oportunity of testing more my new car.
Decided to do a clean start because last time I tested the car not represented real testing. So, took some laps of engine and clutch heating (quite difficult today with the ambient temps) with completely stock setup and finetuning the carb.
First impressions: The steering is so responsive (very quick, too much quick, frightening quick) so reduced some the steering throw and added a little of neg value to the exponential of the steering and things improved.
Figured that some of those frightening fast are caused for some parts of the setup. Done some wrenching to reduce the steering.
Swapped those 37's for 40's on front and rear (sheeesh! how I hate those 'snake' style rims)
37's were too soft .
Went with all the caster shims at the front (what degrees?).
Raised a little the front roll bar up to 20 or 25º.
Front clearance: 4 milimeters.
Rear clearance: 4.5 milimeters.
Rear camber at 2º.
Rear toe-in at stock seemed too much (boy! 2.5 degrees each wheel is a lot - what amount of toe-in are you using? - on the NTC3 used 1, 1.5 at each wheel 2º on some extreme cases) and created too much push on the turns, lowered to 2º on each wheel and things went better.
Other things that I noticed:
This car is a serious rear tyres eater, a set of 40's got a serious punishment and went seriously cone shaped after 7 or 8 tanks. It's normal? Noticed a lot of rear grip on the car (is very difficult to get the rear end unplanted). With 30mm at rear eats a lot of rear wheel (Started at 64, ended at 61 rears, 64 and ended 62.5 fronts). Going to the upper position of rear A-arms solved this?
The brake is very very poweful and not progressive, blocking rear wheels if you got too much brake, ended with a -60% on the brake exponential. Any througs to have a more progressive braking? Yellow pads or stick with stock? some MRX3 boys were at track and barbled with the Mini-MRX3 and suggested those pads.
A boy spared me some pinions and tested 17/21 with stock spurs, things went slightly better, but plan to do some testing with 16/20 on 46/42.
