Hey Jes, sorry to drag up an old post.

What spring rates did you settle on for the street? Is that a G2 poly bushing that is on top of the coilover in the front, maybe a couple pages back? Long story, but I have Ron's coilovers in the front (only) and am trying to get rid of some clunking and excess NVH.

Would you recommend I just slap on the rubber isolator from Colin's Bilsteins on top of the RSR shock body?

Also, how is the poly bushing for the upper control arm? Does it bring in even more road noise? Basically my car is pretty noisy over expansion joints and I'm trying to figure out why.

I think I used poly from Performtek, but your rubber ones from the Bilstein's should work fine. I used stock on a previous RSR.

No, I don't think the poly on the upper control arm adds any noise.

Link clunky noisy? The more racy you go, the more noise... Non-rubber joints, e.g. in front sway bar, in Watts, ... can be more noisy, particular if they are worn. At least that is my experience...

How often do you need to re-lube the poly stuff, if ever? My poly rear end has been grunching over dips bumps since about 3 months after the installation.

Have you gotten wear in your rod ends yet? Luis' front end is about the same as mine, but his car is totally silent over bumps...with 17's.

Also, what spring rates did you decide on? I'm wondering what the best bet is for track/street duties. Does your kit feel a bit under damped on big freeway bumps? On my car and Luis' car, it felt like the car bobbed a bit after a big hit...but maybe that's why street driving is so supple.

As for wear, I would say depending on the compound, every few months as poly is geared more toward track fitments i.e. probably wont be on the car long as you are driving it to the limit every time. The best was to tell is to feel the poly. Depending on how wet or dirty your climate and driving conditions are, i would be more concerned about water or sand/particles penetrating into the surface the suspension component is moving against. as for noise, you may have to lube it more depending on how squeaky it gets. How much louder is it now than it was when you first installed it?
