hi all,
Im sorry if this has been answered already but Im wondering what the advantages are for swapping out the rear trailing arm suspension bushing? I have the bushings (also front +rear sway bar) in hand but have yet to install it. Are there longevity or failures related to not having this bushing?

Anyone have recommendations for shops that can install these at a reasonable rate?

BTW Ive run the Vishnus for two events in 2007 and at both events I got a track record (NASA Norcal TTB #42, Thunderhill+Infineon). This is an excellent suspension for the track. I also drove it last weekend in the hills and it was pure delight. Worth every penny.

Responsiveness - less sponge

Heeltoer, I couldn't give you the technical explanation, but I do know that Paul consider the bushings to give a .4s gain per lap.

IIRC, the rear trailing arm bushings only have a "web" that attaches at 2 points. Any hard track use, and these bushings will break. John Mueller has seen it plenty of times.

You guys are correct about the trailing arm not being solid rubber. However that is not the bushing included with the Vishnu kit. Those are sway bar and rear lower control arm.

Changing the LCA bushing allows the suspension to work more effectively since the poly transmits more force faster than the squishy rubber. Like meanmud said it's more responsive.

Any recommendations for bushing for the LCA since the Vishnu kit does not have them?

I put the energy suspension bushing in. Got it from RRE for $25.

Do the LCA bushings need a press to install? I might do this before any other suspension mods. (Not like I can get the Ohlins right now anyhow, haha)

Yes, definitely. The biggest issue is getting the stock bushings out. You'll need a socket that's the exact same daimeter as the stock one because the bushing rides inside a steel sleeve. If you go too big, you risk damaging the aluminum.

For install, make sure you insert the bushing in the tapered side of the arm, then use the press to get it most of the way in (it will deform a lot initially, nothing to worry about), then use your thumbs to push it the rest of the way.

Stock ones. The poly ones are solid.

24mm Craftsman Impact socket works for me. And yes you def need a press to remove the OEM bushing.
