AW11 Rubber Bush options

Have you considered buying from Amayama? Genuine parts at decent prices. Basically where I go for genuine parts these days if dealer don't have em or too dear. Get the part numbers from Toyodiy or http://toyota.epc-data.com/mr2/sw20/

Prothane bushes are the only option that I have found; I searched high and low for TRD and Cusco hyperball only to have everyone come back to say they are discontinued.
 
Prothane are a lot more durable and measurably harder than stock rubber. TRD were a rubber bush as well but noticeably up-spec'd.
Best place to buy Prothane bushes is Summit Racing: http://www.summitracing.c...rothane-motion-control
 
If you look up some of the TRD part numbers, the bushes share a lot of common part numbers with SW20's as well. Obviously the control arms themselves were different but the diameter and width for the bushing was kept common on a few spots.
 
You are correct also in that Toyota will not sell bushes separately.
 

The poly bushes don't change the suppleness of the ride (IMHO).
 Good quality bushes will improve the feel of the steering/cornering.

Personally I think comparing brand new Toyota bushes vs Prothane, you aren't going to feel much of a difference if at all. The biggest difference will be tired shagged Toyota bushes vs any new bushing.
 
Also agreed a softer OEM style spring and shock is going to keep your ride more supple than softer bushings. Bushings are there to keep the suspension components in the position they are supposed to be in, not make your ride more comfortable.

My AW11 has been running front Prothane bushes since I bought it, but rears were still factory rubber and well worn. I never had any noticeable NVH in the car, but all of the suspension was worn except for the ball joints, so I overlooked for the most part the way it handled.
 
Since then all the rear bushes have been replaced and I will be putting in new Prothane bushes in the front to ensure all wear is even. But I haven't had a chance to drive the car properly so can't fully comment. I know quite a few AW11 owners and most of them have run Prothane bushes, the only comment I've ever heard is they can be squeaky but that may be due to lack of lubrication on the metal insert.

I have an Aus delivered AW11 which I am endeavouring to keep in as original condition as possible.  I have replaced all the bushings with urethane bushes from TwosRUs.  The kit didn't include the rear sway bushes so I used SuperPro bushes there.  At the same time, I replaced the shock absorbers with Koni yellow adjustables which were set to the OEM settings.  I retained the OEM springs.  I have not experienced any NVH and the ride, while firm, is much softer than the ride in my friends' vehicles which have been "upgraded".  Fulcrum Suspensions in Capalaba Qld fitted it all for me (with the exception of the rear sway bar bushes) and did an excellent job repainting all the suspension parts for me while they were out of the car.  I also replaced the ball joints, tie rods and the steering bushes at the same time.
 
When I drove the car away after all the work, I thought the ride was better and more comfortable.  This was possibly because the tired old suspension wasn't doing its job properly.  I agree with DTM that lubrication is very important.

I also have the Konis with standard springs and Prothane bushings. Definitely not harsh. I was actually hoping that the difference with the bushes would be more noticeable as my car is not a daily drivers and is going to be used for track days. The fitting is very straightforward but I also agree that the lubrication is critical.
