Suspension Upgrade on M5

mowblowgo · 22nd October 2005, 21:15

Does anyone have knowledge of what ramafications aftermarket suspension will have on the M5's sophisticated system? With my 996TT I went from stock to Bilstein PSS9's and eventually to Motons. Each upgrade dramatically improved the performance with very little ride sacrafice. Please respond if you have valuable insight vs. an opinion only. Thanks!

I had PSS-9's on my 993. While they were great at the track, it made the car less enjoyable on the street. It it were me, I would leave the suspension stock, as you seem to already have a full race setup on your Viper.

Different strokes...

As of now Hartge is offering a lowering kit for the M5. This kit is great! This is by far the best kit that is offered in Europe for the time being. The M5 is as close to perfection as one comes, and it is very hard and expensive to improve. However, the Hartge kit gives you the edge you need! Go for it! Also try their 21" Classic II wheels and exhaust! Awsome! Tom

Thanks, Does anyone else have experience with the Hartge lowering kit? The 21" wheels look great but I want to track the car a little and fear that those rubber bands will peel off at about 1G.

. Also, after hearing those Kreis-sieg exhaust clips, I might need to wait on exhaust. That kit sounds amazing!

Yeah, yeah, yeah! 21" Hartge's you do not want to track them! Stick with the 19" for that! Exhaust sound is awsome with x pipes!(Export only!). Tom

P.S. I am very biased to Hartge as they have done more than 8 cars for me. Their quality and workmanship is excellent! You drive their cars and you feeling is that this how a BMW should be like from the factory!

The M5 suspensions is not perfect, it is very good but compromises have to be made for the ride comfort, ride height, etc. Some people don't care as much about these things and there will always be room to improve in the aftermarket.

The only question is will anyone develop a coilover setup considering how intertwined the suspension is with the electronics.

If it is anything like PASM on the new porsches it will be difficult to develop an aftermarket suspension other than just springs.

I agree 100% with you. The car is near to perfect with the Hartge setup!

Will! Glad to find you here and that you will be contributing to this board. I have read many of your posts over the years on the E46 m3 boards. I'm looking forward to your E60 project car.

Has anyone used the Hartge lowering springs on the OEM wheel setup? Interested to see the look and if there is any fitment problem.

Thanks,

Ryan

I used them for a while, before getting the Hartge 21" wheels. It worked very well and there were no fitment problems.

looked pretty good, but not comparable to the 21" wheels together with the lowering kit!
