05 evo still on stock suspension. Can anyone recommend a good suspension upgrade? Coilovers/struts

 

Used Bilstein struts and Swift or Gtworx springs. Rear sway bar and rear diif mod are also popular choices. Good tires also help a tad...

 

Can you further explain this rear diff modd?

 

I had elbow surgery a couple days ago and typing with one hand is slow...but here is a link. The first post has a few links as well. https://www.evolutionm.net/forums/ev...ound-here.html

Bottom line is the USDM models got screwed by the way the plates are arranged. There is an easy fix though. I'm not the most mechanically inclined but did the mod in a day.

 

Awesome, thank you. Sorry about the arm, and I hate to bug but...is the improvement noticeable?

 

Yes, it is noticeable. The car drives neutral with a bit of oversteer tendencies. It feels like the rear outside wheel pushes through the corners when getting back on the throttle. I have Diaqueen diff fluid in it now has friction modifiers in it so I am not seeing its full potential. I am going to switch to something without the friction modifiers soon just to test it out.

Here is a quick video I did the day I rearranged the plates....post 295

Rear diff work is $$$. Get a rear swar bar before all if you desire more oversteer without going broke

 

Rear diff work is $450 from TRE or $180 if you do the 12 plates yourself from Weir. That's dirt cheap for either one.

 

Driver mod + tires.

When your friends are able to out drive you with less mods and better tires, then you know what needs to be improved (in my case). Although, with that said, a set of good quality springs couldn't hurt.

I happen to have a set of Swift sports I'm looking to sell.

 

I am not mechanically inclined and re-stacking the plates cost only cost a bottle of rear diff fluid. But, you need tools and space.

 

whiteline bump steer correction kit is a must

edit:if you're doing coilovers you should do this

 

What about with springs?

 

its a solid upgrade if you're lowering the ride height at all. read this and it will explain(also a great thread if you do not have access to a shop press):

if you are just going for looks and don't car about handling then forget the bump steer kit, you can worry about that later. all depends on the the OP is trying to do

 

Totally 100% going for improved handling. I wouldnt spend that kinda money for looks.
