I read a lot but still confused :s

monodose · 10-27-2005, 12:09 AM

My E46 M3 is on the way and still can't figure what suspensions shall i get

I'm looking for something that will give great stability around corners and for street use, i will be tracking the car also, the main thing I'm looking for is taking corners faster (street and track) and i mean FASTER

I read a lot about it here, can i narrow my choices to PSS9 or Ground control?

vaio76109 · 10-27-2005, 01:04 AM

For track use GC>PSS9 any and every day of the week.

Also look into TC Kline which I consider an equivalent to GC.

I just checked GC's Site and they dont ship internationally

vaio76109 · 10-27-2005, 01:45 AM

In that case http://www.tcklineracing.com/suspension.htm Id go with the S/A coilover.

why S/A not D/A?

vaio76109 · 10-27-2005, 02:42 AM

Do you have extensive experience using colilovers? rebound and bound adjustment?

If not the DA will be overload for you, the SA is still plenty of adjustment. But if you have experience tuning suspensions go for the DA.

what ecperience do u mean? can't i learn it?

well to be honest, I want the corners and long turns to be to my advantage on the street and on the track yet be street driven

and i'm really not that experienced with coilovers

I suggest hitting the track without mods first. The M3 is a VERY capable car, you should learn its stock limits before upgrading it.

Mr Paddle.Shift · 10-27-2005, 01:48 PM

D/A offers more adjustability if and only if one knows how to fine-tune the suspension. I had a PSS9 S/A for about a year now. With more than 20 track events under my belt, I still opt for new set of coils + stiffer springs with S/A setup. Hey no one is judging you or anything. Everyone can learn how to work with D/A setup. Would love to hear from your involvement in motorsports in Dubai. Maybe you can share with us your chassis tuning knowledge with regards to CG location, roll center location, camber, toe, caster specs and their practical relationships to over/understeer, lateral and longitudinal g-force.

I am actually interested how aerodynamic downforce correlates with roll and pitch. Let me know if you have something to share.

And definitely go SA if you do decide to get them.

I know that no one is judging me here, i was asking a real question and i wasnt sarcastic as all

This pic is a bit of my involvment in motorsports

See, that clears things up doesn't it?

How long have you been involved in this sport? What kind of motor is in there?

There a couple of folks who race their BMWs and lurk on this forum. I hope they can offer you some valuable advice on choosing between SA and DA. Also look for PineCone, Jim44 for advice on Bimmerfest.com too. Both of them race cars.

My personal take is if you're turning your E46 into a dedicated track car, the DA setup is the way to go. But for spirited driving on the streets and occasional track use (not drag racing), then SA is good enough.
