OEM were Tokico back then. But now Suzuki's have Gabriel as OEM as per my knowledge.
Gabriel with *stock springs are best followed by SNA CNG springs (if buying stuff from junkyard is not your thing), but springs of SNA are high and stiffness is reasonable. Is there any better stiff springs (new preferably) available?
Tokico are harder than Gabriel. KYB has a lot of fakes, so i did not try that.
What springs are you using? Are they hard or soft?
Gabriel is very durable, last 4-5 years easily.
Edit: Stock springs are best. Addition of spacers is better than replacing springs.
