Wanting to start work on my sw20 and starting to get some parts ready.
I decided id start by getting some new suspension bushes and found this kit http://twosrus.com/catalog/product_info.php?cPath=22_61&products_id=431 on this forum.
Just wanting to know if there's any similar kits out there? and if anyone's done them is there anything i have to look out for while im replacing any of those bushings? 
Any advice would be much appreciated. 

For value for money, and improvement per dollar spent, this would have to be the very first step for anyone.  The quality of the product is excellent.  I haven't found anything comparable.  As mentioned in the catalogue the point to make sure of when ordering is the size of your swaybar.
 
Are you doing the spanner work yourself?  You will need access to a press for removal of some of the old bushes.  If you are doing it yourself, and are willing to spend some time on the job, consider cleaning and painting your suspension components while you have them off the car.
 
Also, a full wheel alignment the job is done is essential - you'll be shifting a lot of geometry around, and our cars respond well to correct alignment.

Thank you so much dennis the menace.
Im apprentice mechanic so im doing everything at work. Starting the timing belt on monday so ill measure the bushes and order parts when i get home.
And thanks so much making me aware of painting the suspension, I honestly didnt evan think about that. 
Really appriciate your help.

No problems, Ace.  Painting the suspension might not make it work any better, but every time you look under the arches you'll go  "Aaaahhh, that's sweet!"
 
If you really want to get carried away, it's not too much extra work to drop the exhaust and then remove the rear subframe for cleaning and painting.  Makes for a really nice job . . .

You know what, I probably will do that i want to learn everything i can before i finish my apprenticeship thank you so much bro

you should double check your sway bar size though, as I believe they did come with different size even with same year model (that's what two'r'us website mentioned anyway).

Many of the stock '90 - 92 bars are 18 mm diam and the later ones are 19 mm. 
It is important not to squash the bushes too tight when fitting, so it is important to get the right ones.
 
Also consider fitting swaybar reo plates under the front brackets if you don't already have them to avoid chassis cracking (see Delta V or Twos'R'Us) 
 

If interested I've got a set of front and rear sway bar bushes - unused. I thought I had standard sway bars until I went to fit them. I've also got a bushing for one of the front suspension components. I had the 92+ revised suspension but the set I got was for the 90/91 suspension. Its the bush at the front of the wheel axle that moves the axle forwards or backwards (If that makes sense)
 
PM, if your interested.
