Odd ball question. Anyone know what the durometer is of the current available A arm rubber bushings? Looking at mevotech MK6253. I'm guessing they are the equivalent of any stock IROC/WS6? Don't want something equivalent to a 85 Berlinetta lol.

I'm at stage 2 of my suspension now. So far waiting to go on/ordered:

Koni Yellows
UMI 850lb weight jacks
UMI strut mounts
UMI tie rod adjusters
BMR 160 lb rear springs
Proforged (stock style) balljoints
UMI on car adjustable panhard poly/roto
*edit* Currently has TDS wonderbar and J&M rear control arms with polyball (3 piece) bushings

Setup now is stock springs with 1 coil cut and KYB Excel Gs. Tie rods and idler arm have about 5000 miles on them. Will keep them and install a new MOOG center link.

Was heavily debating getting new UMI or DS A arms with Delrin but need to draw the line somewhere ($$$). Option 2 was GW del a lum in the stock arms but now I'm thinking just go rubber. Reasoning the car is driven all the time will trade some handling for less NVH.

 

I would guess a Berlinetta bushing to be the same as a Z28 and IROC from the factory. The differences were in springs, swaybars, shocks, struts, swaybar end link bushings, and tire sidewall height.

 

Yeah Im just going to order them. I think it was 1LE cars had a better bushing in the rear control arm? Thanks for answering

 

Unless you are racing against a clock or track position, rubber bushings are the appropriate choice. Harsher (more performance) ride can be obtained later with tires, struts and springs as needed.

 

I'm not, that why I'm going with rubber.

 

If you don't, you'll probably regret it down the line. Ask me how I know, lol. And you're correct about the 1LE/durometer.

Yes, I digressed. Again. Ha!
