Ferrarist, are you sure that
- 26mm anti-roll bar in front, redrilled another hole on it, for more stiffness. Had uprated rear ARB but IMHO standard one is OK.....(have intention to try with rear ARB disconnected)
is what you meant not the other way round? Otherwise, this will open a whole new discussing (IMHO). I cannot see how soft rear ARB or removing it completely would help cornering. It is the other way around on a Coupe and it's been said many times before that this is the single best possible mod - stiffer ARB.
Yes, i'm sure......
I don't know why only stiffer rear ARB is considered as "best possible mod".....Coupe suffers front understeer - stiffer rear ARB only will make things worse. And there is many suspension books that states principle like this.
My experience.....MY EXPERIENCE - i tried:
Standard 22mm front ARB, Whiteline rear: More understeer
26mm Eibach front ARB from my trackday Alfa 156(fitted via plate to the shock Lancia Lybra arb style), Whiteline rear - little bit more stable front and rear end - neutral balanced car - better laptimes than previous setup
26mm front ARB with standard rear ARB - little bit more understeer, but improved laptime.....i was very suspicious about this result and make few days with this setup - driver's feeling sometimes may be wrong, but the race chrono - never.
Then i redrilled another hole on the front ARB, nothing changed rear - same feel, lit-t-t-tle bit more speed in the corner.
Same ARB's but less stiffer springs in front - massive difference - car pitches more, braking improves due more weight shifts to the front, better turn-in and mid-corner as well.......bit of understeer on the exit, but it can be cured with different driving style.
All that was done with same tyres and pressures.
Again - my experience. I designed below Locost all by my self, using same principle - stiffer front ARB, softer springs as possible - no rear ARB - and it works fine.
