Evening or rather morning you lot :)

As most probably know (bored pooless ;)
I've H&R arb and lowering Spring and OEM CSLd
My MR.

Now, will it be ok on its normal geo done at BMW not too long ago, but before mods, of shall it need one, and if so which??

Cheers in advance
 
A little lowering will result in a bit of additional camber. Did you do both arbs? They on their own won't make any difference to the geo, but they will alter the behaviour of the car (more oversteer or more understeer, depending on which one you did or how they both complement each other if you did both). You may want to adjust the geo to account for it.

Bottom line though is the standard settings will likely be absolutely fine unless you're tracking it or regularly exploring the upper limit of the performance envelope, and are really noticing handling traits which you want to try and dial out. Do you find the car understeers or oversteer more? Do you find you have to 'drive around' understeer or manage the throttle too much to prevent messy oversteer?

Genuinely if you're not noticing things you want to start altering with the handling, I'd just stick with OEM geo.

Morning and thanks for taking time to reply

All above no no and no:)
Sits flat as a pancake and grips like a fat kid to a chocolate bar
Even upper end I sit calmly and relaxed one hand on wheel other on stick, I'd never track my car.

I'll keep an eye for uneven wear to tyres then:)

Thanks buddy

No problem chap - I'm sure people will have different views, but my opinion is if it's all lined up and tracking properly, the tyres aren't wearing badly and you don't have any issues with how it drives, why change it?! :)

Enjoy!
 
Totally agree
Just wondered when I saw custom geo on a lowered car
But no handling issues at all

Lowering will also result in some additional caster. But that is normally not correctected unless you have casterplates or so.

BMW spec for alignment is 68kg in each seat (seat in middle position) and 14kg in the boot
 
Just for info, I got the OEM CSL Geo settings put on mine (pulled the camber pins) and personally for the £150 it was worth it...
 
But that's for E46 car that's my only issue
I'm going to Bmw tomorrow so I'll ask:)
Ta buddy

My copy of TIS only mentions loading the car if the ride height is out of spec. Which seems really odd - I would certainly want the car at least weighted for me.
 
In my TIS copy it says that the car must be loaded according to DIN (those weights) and that the car then must be verified for rideheight. When that is ok, alignment can begin.
When thats not ok, there is something wrong with shocks or springs and that has to be sorted out first.

Thats what my copy says (more or less, its in dutch) but that makes much more sense.
