I fitted some H&R -35mm springs back in July (great service from DPM) and from the point they were fitted noticed an increase in road noise from the front of the car. This isn't an issue as with a 'harder' front end would have expected more noise tbh.
One thing that I wondered about (at the time) was the fact that some of the coils on the front springs touched even before the shocks had been put back on the car (and put under normal 'sag' from the cars weight). The workshop commented on this and said that he'd not seen this on Eibach or Koni springs which he normally fitted.
Now, 2 months on, they have settled a little bit - stance looks great, but the road noise has increased a bit more and when I look into the arch it seems that lots of the coils are now touching (as if there are too many coils).
Most folks say that H&R springs are very similar in 'feel' to normal S-Line springs too, but I have to say I think the rears are VERY hard when compared to the original OE Sport springs and seem to transmit every bump in the road into the car. I know the roads around Bristol are particularly shocking in places, but I find myself bracing for impact after I feel the fronts go over something.
So onto the questions...
1) Is it normal that the coils of the spring touch?
2) Is this an issue for the car (premature aging of other components based on the transfer of shock forces into the car)?
3) Does anybody else think that the springs are REALLY hard or am I just getting old?
