Cheers Cake,
I did plan on using the oven at work but ive ended sittin the head lights next to my wood burner at home, then working it a bit..
It not a quick job but it should be well worth it imo
I had hsd's on my m3 and you could set the ride to be as soft as oem if not softer if that's what you were after... Mine were the early model and they looked pretty rough pretty quickly but worked really well
I had 35mm h&r's on my m3 but they were too fat so I chucked on a cheap set of no names 30mm's.
My bro is now running my m3 with those spacers.
I think there will be a set of h&r's in his xmas pressie haha
