Hi Guys, I'm half way through doing a brake upgrade on my KE-30 two door coupe. (early Corolla's are not known for they amazing brakes) I researched all the other options people have posted on here over the years. I've managed to obtain a set of front RA-65 Celica struts, complete with brakes & LCAs. These appealed to me, as I get the bigger hubs & bearings on the front wheels, & the big vented disks. Mate it up with a Pajero 1" bore master cylinder, and my KE-30 should stop on the spot. The RA-65 LCAs & strut lengths, are the same as the KE-30s. The only major mod required is the replacement of the lower coil perch on the RA-65 struts, as the strut towers on the KE-30 are too narrow for the RA-65 springs, which have an OD of approx 160mm. Lots of posts say that there will be postive camber issue with this type of upgrade, but my measurements to date indicate that, if there is a problem, it will be small, & can probably be corrected with a camber adjustment plate or slightly longer LCAs. I've already got 14" mags on the KE-30, and the wheels fit easily over the RA-65 hubs & brakes, with plenty of clearance to the lower spring perch. I originally decided on KE-70 front coils, as they have a smaller OD (125mm) than the standard KE-30 ones at 145mm. This would give me maximum room for movement in the KE-30 tower space if camber adjustment is needed. I obtained some "donor" KE-70 struts & have removed the lower spring perches, and opened them up to fit the 51mm OD RA-65 strut tubes. I was without top spring caps for the KE-70 struts, but I got two which are actually AE86 top spring caps, which I was told would fit the KE-70 springs. However, the AE-86 spring top caps are slightly too small for the KE-70 spring. I assumed then that the AE-86 front coil spring must be even smaller in OD than the KE-70 one. A bit of research on Google has turned up that the AE-86 front springs are 120mm OD. As I haven't purchased new King springs as yet, I thought I might as well go for the AE-86 coils instead of the KE-70s, as I've already got the AE-86 top spring caps, and it will result in even more room in the strut tower. The only question is, will the bottom of the AE-86 front coil spring sit snuggly in the KE-70 lower perches ? If there is anyone out there who can confirm that an AE-86 front coil spring is 120mm OD, and can advise if it will fit the KE-70 lower perches, I would be most appreciative. P.S. I am documenting this upgrade with pictures as I go, so will post it all on here when completed. I have a donor KE-55 set up in my garage that I can experiment with, then swap it all over to the KE-30 when I get it right. P.S.S. The only other question is what multi pot calipers are around, that will replace the original RA-65 ones, without any mounting bracket changes? Cheers Banjo
