Reviving KP30: Handling Pt 3 -coilovers-

   The next step was to have a decent ride height but I have to admit that there is no specific calculation or measurements on this purpose. It just happen that I have a set of used adjustable coilovers taken out from my Perodua Myvi/ Toyota Passo. The spring rating was 6.5kg/mm in the front and the OD of the strut is about 2 inches.



I took out my TA22 struts and compare the OD and length for both struts and lucky me they have the same OD. The length of the coilover strut is about 1.5 inch shorter than TA22 struts.


Moving on the fabrication process, nothing special here just cut the old TA22 strut and remove the catridge casings. Inserted the coilovers onto the base around 1.5 inch deep and weld them from the bottom. I assume that Im going to be very low with enough suspension travel.





After the welding and skimmed disc rotor.


Then I stripped the casing paint out prepare for its new paint. Im using Acid#8 for the base metal primer to protect from rust and good bonding with the finish paint.



Same goes to the disc rotor 











I realize that another problem rises up where the top mounting doesn't fit with the piston shaft. The shaft is about 0.3mm smaller from the ID of the top mounting so I had to mod some tapered washer and insert it in place just for a temporary fix before I can find any appropriate metal bush. That will do the job for a while :)



So the finish product, the KP30 drives great on low height with enough suspension travel and the brakes feel smoother after the rotor been skimmed.
