The best is 15inch. Hehe..

Yup.. Either you lowered, or put bodykit. But 16inch using 50 series already so bumpy. If put lowered again, scare more bumpy..

I checked the height. It only 2 and half finger for the front gap with stock absorber and spring. I guess not really high. haha

Haha.. I tested a same car (waja cps) but one is 45 and another is 50. 45 is so bumpy like no absorber. Haha. 50 series is good enough. Unless you get the soft side wall, then it will more comfort than performance.

how many people here using GAB spring? If compare with R3 spring, which 1 is better?

Yes.. Because for oxygen sensor reading is digital. It always lean rich lean rich lean rich.


Beside sphiroth setlle the rattling sound with SAFC II, still got who member here solved the 2.8k rpm rattling sound?

from 1st to 5th gear also got. From 2.8k till 3krpm.

Mine getting louder and louder. But I wonder y no ppl complain at proton sc.

What I suspected is related with metal. When cold, the sound is minimal while when it hot then the sound is so loud.. Really da*n frustrated with this problem even proton don't have bulletin on this.

hhaha... what the use of SAFC? hehe

@KLIA, got ask how the SC ppl do it?

Erm... Then I try to tune it become slightly richer.. If can, then I will install adjustable fuel pressure as it cheaper compare with safc.

Can you check back what part they had change??

Today I check for the rattling for 2.8k. I advance the ignition timing and re-adjust the air fuel mixture. Surprising the rattling sound become lower... I try to make it more rich, but can't. the car lost power..

the funny thing I saw today is, got a cps owner fuel rail get crack because of adjustable fuel regulator. So advice for the adjustable fuel regulator user, pls change your fuel rail. Or else, don't set to high pressure.. =)

Actually still can set high if the injector still standard. Cause different pressure the injector spray pattern is different. But doesn't mean the higher the better..

Wow.. 4.5 bar.. crazy man.. haha...

I done port and polish to my cylinder head today.. Then fix the VIM problem as well.. Too bad last minute cannot get a header. Or else, I sure throw my cat con away...

No cost. I removed and do it by myself. Half day siap. Hehe. Dunno can get increase of hp or not. Only know all port is so smooth and licin.

have you guy noticed after using fully synthetic oil, the car engine sound rougher compare with semi? I feel it rougher at high rev...

New upgrade. 2.2" mandrel bent stainless steel extractor and bullet.
