    Hey up chaps, newb here..

    Got a 330ci sport on a 51. Just wandering what folk are doing to get more grip on the front. Obviously it has been designed to understeer with 225 on front and 255's on the rear.

    I presume M3 alloys and tyres don't fit due to arch problems, and obviously the camber is set up boggo and would benefit from a bit of negative being dialled in.

    Have tracked it a few times, just on standard suspension which generally can be controlled as long as you're super smooth - still lifts rears easily mind, but certainly find front end to be the limiting factor...

    I am also aware that i could spend a fortune putting coilovers on and loads of trick suspension bits but still end up wanting the extra power of the M3 so at this stage i don't want to get involved in that!!!...

    Ta...

    You need to balance the front with a bit of throttle to stop the understeer when you are really caning them. My local roundabout was always a prime source

    Cheap tyres will cause really early onset of understeer though.

    I've got Bridgestones on chaps and have had Michelins previously..

    I know about balancing the rear, the issue is that the 330ci is designed to understeer because that's safer for most folk than oversteer!! - Which is of course a lot more fun!!

    The design of having 255's at the rear and skinnier 225's at the front is primarily there to make the front end go before the rear and make the car 'safer' to drive for regular folk... If they sent it out with the same tyre all round it would have immense front end grip and "MOST" folk would just spin round in circles!! - Without traction of course..

    Like i said, i just found the front end to be the limiting factor in overall corner grip.

    When i drive it like a hooligan and slide it about on edge then the balance between front and rear is correct or should we say 'SAFE' for this car. Still a load of fun don't get me wrong!! But doesn't get you round the track without a lot of tyre wear...

    I did try messing about with different tyre pressures a bit to balance it but just found i got more wear on the fronts....

    Could just be being fussy... But you don't know till you ask!..

    I had a lot of front end problems in mine, lowering the front and fitting adjustable top mounts solved it. Iv got about 2.4 degrees camber on the rear wheels and 3 degrees on the front, Toe angles still factory set, 10mm drop on the rear and 80mm drop on the front. 255 tires on the rear, 225s on the front and she handles like a dream.

    To-do list:
    1JZ-GTE conversion, Z3 rack, poly bush, Respray.

    Done list:
    Short shifter, M50 manifold, Headlights, Induction kit, Front+Rear strut braces, Carbon badges, M3 diffuser, Illuminated gear knob, Body work (Rust ETC), Smoked LED Rears. Trims painted black, 18 button OBC, Dash rings, Adjustable rear camber arms, EBC brakes, New rims, M3 mirrors, Adjustable top mounts, Coil overs, ICE, Exhaust, LSD.

    80mm on the fronts ? Crikey... But i certainly know with a bit of -ve camber it will make a world of difference and stop the rapid wear rate...

    Is yours a 330? Also, did lowering the front end that much not have detrimental effect on the anti roll bar?..

    Mind you, a lot of people swear by only using a weak anti roll bar for bumpy track or road use....
