I have been using MeisterR Coilovers on my Altezza for the past 5 months and they have been great.
Not hard for a daily drive, but can stiffen up if I want to do some "spirited" driving.
Are they worth the money knowing i will only be using them for road going purpose ?
For me, they have been great. My standard suspension is about 100,000 miles old and you can really feel the difference when you but new suspension on.
Stiffer linear rate springs also makes the car handles much better and become more predictable.
Is it easy to set coilovers up ?
Coilovers is a complete replacement, you take off the old damper unit and put in the new. You won't even need a spring compressor.
How do you know exactly how much lower you have gone ?
Don't know, just lower it until it looks right. But my rear is 20mm higher then the front, makes the car feel more balanced when I drive it.
Is it worth paying the extra and saving for a set of Tein's or is it much and such the same thing ?
I actually don't rate Tein as most of their coilovers are TwinTube dampers. For the price they charge, it should be MonoTube.
But then their MonoTube dampers are a lot more expensive.
Yes, I know I need a new set of wheels.
