I’m looking into what options there are for the “short shock” replacement on many of the other Daihatsu models, to see what might be applicable for the M1XX Sirions.
It seems the Hyundai Excel X1 / X2 is the go to short shock absorber option when moving to a lowered height. Of these it looks like the most common is:
- KYB Excel-G (p/n 343183)
However there is also options from Monroe, Webco, Gabriel (two options a “Guardian” and a higher Spec “Ultra”), and no doubt others.
Is anybody able to share experiences with these shocks with respect to track-work?
Are there options from other models that are known, that may have more sports-orientated offerings?
Has anyone installed the shorter shocks on the Sirion model?
A bit of background into why:
The BC Racing Coilovers in my M101 are 3kg/mm springs, and I’m after higher rate ones.
I’ve got a lead on high rate springs with the 95mm ID applicable to the Daihatsu’s (basically 4K upwards in 2kg increments all the way to 20K), however they’re drastically shorter than the factory springs and shorter again than the rear springs the BC’s have. Factory ~300mm, BC 225mm, High Rate 150mm. Additionally I won’t be able to use the height adjustable collar as the BC springs are custom 118 top ID and 95mm bottom ID. So without the height adjustable collar these springs will provide whatever height they provide. My concern is that if you do get a wheel lift while cornering the shock length will have to be such that it won’t allow the spring to become un-captive. Hence the possible option of shorter shocks.
I’ve also approached BC for higher rate, to which they’ve said:
“Unfortunately the only option they make is the 3kg. This is due to the custom design of these springs”
So they’re no further help.
I’ve reached out to King Springs who can do custom springs to order.
Thanks in advance.
