Tbh, NCP150's shocks are prone to faults by default. The spring is just too soft and there's a lot of play involved, especially for the rear shocks.
There is one year warranty on these.
Around 400-500 depending on location. I didn't get it because nobody is a reseller here. It is my 2nd choice tbh.
If not mistaken, there is only one OBD slot so you can't plug in more than one device. If you decided to have a temp. meter or some sort, then the auto flip will have to forgo.

Hi bro, how much is it for the Ultra racing front strut bar and rear stabilizer bar?

Can't beat Preve, Suprima, or even Persona that's for sure. The multi-link rear suspension is one of the reasons why these Proton models are known for good handling even without mods.

Also, the front struts bar comes as a standard for almost all of their cars. Talk about $ savings!

Looks like your mods are similar to mine just that I kept my thicc CC5s.
It's comfy but not the best in wet nor traction. Squeaky at best. What's the price for UC6 and CC6?

Hopefully a full load at the back will not bottom out like the original spring did.
Btw, the rear bar is the solid or hollow one? That upgrade will be one of my next ones.

It squats lower without being too much. Just right.
