I just put in a full set of Ralliart Group N bushings (adam at Z1 chased them down) and now my shifting is super smooth. No more of that rubber band action as the driveline moves back and forth when you shift or get on and off the gas.

I don't know which ones helped the most because I put them in all at once. There are 4 in the back for the rear diff, and 2 main engine mounts and a rear engine/trans mount.

That's the good news - cheap fix for a sloppy driveline. On the down side, my fillings are loosening from the extra vibration that coupled to the chassis - especially to the steering. It's most pronounced at idle, and almost goes away above 2K. My last fun car was a full up Production GT Mazda 323 GTX, so I'm kinda used to this stuff and quite glad I made the change! Thanks for chasing down the parts Adam!

 

how much are they??

 

what are they made out of?

 

I think around 160 bucks - i had some other stuff on the order. Check with Adam, I'm sure he has the bill around.

 

At first glance, they look like the stockers - but they are not "voided" as much and they use a MUCH higher durometer rubber! They're sold by Ralliart for the Group N rally cars.

 

you said it replaces the two main motor mounts too??

 

I'd like some polyurathanne ones.

I bought the kartboy ones... those should be in soon but I think it's only like 3 or em.

 

They have Group N bushings for almost everything. The mounts, insulators, suspension arm bushings, sway bar bushings etc.

 

what is the website?

 

www.z1auto.com - I don't think they have them on the website - just give Adam a call.

 

thanks!
