im a newbie at this but im wondering. i need to replace my rear trailing arm bushings should i go with OEM replacements, energy inserts or hispherical's? my car is already a bit slide happy in the rear so any info will be apreciated.
set up
92 SI hatch
k20 motor
f2 suspencion
front benen tower brace
rear spoon tower brace
ITR SWAY bars
SK2 rear LCA'S
ASR sub frame brace
tires are 215/45/16 azenis RT615
also how much tire pressure for time attack on a short curvi road?

 

I don't know of anyone who likes the Energy Suspension poly trailing arm inserts. Spherical parts will be expensive and harsh on the street. I like the Hardrace/Megan racing OEM-style rubber bushings that are stiffer than OEM. They are pretty reasonable, too.

 

OEM or Hardrace/Mugen are your best bet. ES trailing arm inserts have a potential binding issue, and can present handling problems. Best to just avoid it. While some people have no issues with sphericals on the street, I think it's stupid, especially if you have them in only one location. Pretty much guaranteed, they'll require more attention to maintenance, and could wear out quicker.

 

hard race are looking pretty good then..what about having a tail happy car like mine what can i do to fix this?

 

The most likely culprits for a "tail happy" FWD car, in order (IMO):

1. YOU. You are a self-admitted noob, and thus are making driving errors. Most likely this is lifting off the gas mid-corner (also called lift-throttle oversteer), braking mid-corner, or both. That's ok, because everyone is a noob at some point. Get with a much more experienced driver, have them ride with you and keep an open mind to their criticism/suggestions. 98% of the time this is the case for a car setup like you describe (which is in itself, fairly neutral).

2. F'ed up tire pressures. Too high or too low in the rear can result in rear instability. With experience, you'll figure out how to setup for a desired amount of rotation. Until then, keep it even front and rear.

3. F'ed up rear trailing arm bushings. This is a way touchier and less common thing, but when the stock bushings are old and torn, fast, severe unloading of the rear can result in snap-oversteer. Think hard braking zones, where the rear would be getting light.

4. Bad alignment. This would have to be pretty screwed up to make the car a handful, but it can happen, especially if you never had it done after putting those F2 shocks on.

Cliffs: Check your bushings, check your alignment, and then have someone teach you proper.

 

Your best bet is Hardrace. They are a complete replacement bushing made of solid rubber.
