Poly bushings too stiff?
What's your issue with 4:88s?

Can of worms about to be opened, but Poly bushes are not effective with the lower wishbone alignment system that we have, by the very nature that they are designed to deform less. Alignment is much more likely to get knocked out, and NVH is increased. They were amazing on my M3, and the MR2 but they was a different setup (no adjustment cams on the lower arm). In theory they are fine for the rear and uppers, but I prefer the feel of OEM rubber. I know about 10 people will now probably pipe up and say "I have polys and it was fine" I don't really want to do there. I sang their praises too when compared to the old factory bushes.. 3 or so years down the line, and manually cycling the suspension post alignment and I decided to get rid. Truck was transformed!
4.88s just seem pointless in my application. It doesn't accelerate any faster (saw under 0.2 second difference over a standing quarter) and just means that the revs sit higher on a long motorway drive, and I end up using more fuel, and going more deaf. I guess it picks up ever so slightly better 0-30, but if I stomped on it on 4.10s the rears would spin anyway. For me the parts were more expensive than most, as I and to get them shipped form the states, and pay import duty on them, so not an issue as such, just not worth the money for the little to no improvement in my application.
