The HD's should be fine with the BMW Sport springs - the Sports are quite a bit shorter, and since the BMW Sport springs are set up for less than a 1" drop, the HD's should work out fine. The Boge's are working out splendidly, no hard bottoms, and that is on NYC area roadways.

I am very happy with my wheel and tire setup at the moment for handling and ride, considering where I live. I don't fear that I will bend a rim on city streets, and I think the ATP type 5's look great on the car. The wheels have held up very well, though I remember Sean Horton had some finish problems with his 17" ATP's a couple of months ago. By the time I am ready for new tires, I will likely be living further outside the city and will at that point upgrade to a 17" package. If I have not yet bought a set of Throwing Stars, I will probably buy either 17" ATP type 5's, or possibly Breyton Inspirations. There are some very nice e39 540 wheels in 16" that you might want to consider.

Micha,

I've enjoyed and do appreciate all of your suspension info regarding Tourings. Given that the low slungs are a bit shorter than stock, is there any problem using them with Bilstein HDs, as opposed to the shorter Sports?

Please keep us posted on your sway bar hunt.

Are you happy with your wheel choice? I've been considering that wheel as an option. My preference is for a 16" BMW wheel, but the options are limited.

I am running BFGoodrich gForce T/A KDWS, they are all season Z-rated (actually W-rated) tires - the SP5000's were my second choice. I think they are great in all conditions I have encountered so far. The tread was aggressive enough to move me in the snow the few times I had her out in the snow this past winter, though I have the luxury of other cars for the winter. They are great in the wet, not too noisy, good turn in, better wear rating than the SP5000, and they were slightly less expensive when I bought mine. They are only made in 16 and 17" sizes, so if you want to stay with the stock 15" tire, they are not an option. I did chop up the outside of the outer front treadblocks in some autocrossing. I see it as a badge of honor ;)

Other things I have been toying with, at least mentally - our Touring front sway bars are 25mm, which is the same size as the M5 bar, through the M5 bar is a different part number and is probably stiffer. The rear sway has some room for improvement - the stock T bar is 15mm, wiht a 16mm sport bar available. The M5T rear bar is either 19 or 20mm (two different ones available). I will be looking at upgrading there after I remove the rear self-leveling.....

Has anyone tried any of the combinations of springs/shocks mentioned a couple months ago. I know MicahO is using bmw/boge up front, but has anyone tried bmw/bilstien all the way around. Just trying to get some feed back before I'm stuck with it. If anyone has some input please desribe the rides pro's and con's. By the way, anyone have good choice for a high performance all season tire(Z-rated). I was thinking about the dunlop sp 5000, but didn't know if they were maybe to soft for the corners. Any help would be much appreciated. Thanks, Drew
