How does she drive now that everything's done, compared to the standard E28 M5 set-up?
What's that last picture all about?

The spring rates are the same as the Hartge H5s-24. E28 M5 with M88 tuned to 330bhp. Front springs are 264 which is the same spring rate as the M-Tech short spring (2 red flashes on the lower coils).
Rear springs are 236 instead of 214 of the M-Tech spring. E28 M5 is 207.
This past weekend I have been driving the car over as many speed bumps & uneven surfaces to run them in.
My notes to myself are that the rear springs are absolutely perfect. The ride comfort is still present in abundance but the extra control I feel from it is just in a different realm from what I have run before.
The rates I am running are the same as the moderators on another board. They raved about them & there not wrong!
The front now feels locked into the straight ahead position. The weight of the steering off centre has increased which gives more feel to my finger tips. It turns in better & tracks like an arrow at speed. It feels like a much more modern car...If that makes any sense.
The top mounts make a big difference. I'm running them on the "-" position. Check the pictures.
Incidentally I'm running a 1mm smaller front anti role bar than the standard e28 M5 as it is well known that at lower speeds an M535i will out handle it on account of less understeer. I still get the same control at high speed as the standard bar but once again less understeer.
The tires I'm running are epic! They is no tire noise, The rides comfy & when they warm up it out handles a dog. Handling wise I have hit the nail on the head. Could not be more happier. Also from the pictures you cannot really tell if the car has been lowered or not which is what I wanted. There is ZERO rubbing from the wheels under any condition...eg: Full tank, two people in the rear, speed humps (It's all about the offset).
I got my measurements spot on
Last picture shows that the rear bulkhead boot trim still fits even though I'm running the Alpina long range tank.
Next job is the body work but at the moment I'm just enjoying the fruits of my labour. Built not bought.
