Re: rattle in dash

Pretty much all third gens do this. I blame the plastic pieces rubbing againt other plastic pieces. Over time The plastic warps and causes rubbing. I think that installing little pieces of rubber or similar between mounting locations, would help a bit, but I havent tried it.

Re: rattle in dash

One of the bad things about cars from the 80's is the build quallity. Every 3rd gen I have owned/ridden in has had dash squeaks/rattles. Some cars a very noisy and others are somewhat quiet. Bascily the entire dash is made of plastic, it's going to flex with the car. Subframe connectors help a buch with this.

Ive owned 2 IROCs--1 without subframe connectors and 1 with and I can tell you the one with the SFC is a totally different car!! NO rattles whatsoever--I highly recommend getting them if you are going to keep your car.
