Does one have an advantage over another im assuming the triangulated has more support, but im new to the import game so i was curious if theres something im missing.

 

i remember the spare wheel gave rear structural support...
it got rid of my squeaking noise.

Ingalls makes a good one. but i bet u can make your own cheaper and easily.

would be nice if theres another bar going across to connect the lower part.

 

Both are sparkly bits that don't do a lot structurally. Have you ever looked at your rear shock mounts? There are no towers, they are so well-braced.

 

What will make a difference is a rear sway bar, proper dampers, then springs.
Coilovers are generally for looks unless you spend good money.

 

So I shouldnt even waste the money I guess well I'll spend that money on some good springs.

 

Any suggestions for autocross? What type of springs I should use?

 

The forum has a motorsports section fyi that would have a lot of good info on that. For auto x I know a few guys had good success with the trd springs and struts.

 

Thanks I'll search for it

 

For autox it's better to go stock first. Then figure out what you need to change to make it better. Don't buy lots of suspension parts without knowing what you're tuning; you may end up with a car that handles worse. That said the general consensus is that a thicker rear sway bar is very beneficial for autox.

 

Any lower than 1.5" lower than stock will start to degrade handling. I think the TRD and H&R are as good as you can get, spring-wise. Dampers like the TRD or Tokico will help handling also.

And they're right, a rear swaybar will decrease understeer.
