my car when i got it a year ago came with Megan EZ streets for the Supra. not sure what spring rates are but compared to stock suspension they're decently stiff. never bottom out dropping off road construction bumps or bigger drops, do bottom out on tall speed bumps though if i go a little faster. don't have them on the stiffest setting, i think like 4 or 5 away from stiffest. i think they're great, never driven with anything else except stock and it's a huge difference. great price as well (even though i got em with the car)

don't know how old they are but sometimes the rear pass side one does a little click noise on extension. very rarely, sounds like flicking your finger on a can of soda. other than that, no problems at all.

 

First off sorry to revive this thing after about a year or and a half but....

I just recently purchased an SC300 running 30k Front 12k Rear and I'm trying to figure out the best setup for re-valving and setting a new spring rate on the front. I have zero experience as all of my prior experience is with 240s. My old s13 was running 8k/6k so this 30k business kinda freaks me out my LS400 is running 20k/18k but its a big body and stanced so that's not really a good comparison.

I was thinking something like 18k/12k or 16k/12k, anyone have any suggestions
I'm gonna be using it for light drifting, some road coarse, and touge stuff

 

I have 18k 12k on mine. I like it. But I've been told you need stiffer rates for drifting.
I built my car for high speed grip, and this works very well for me

 

Another narco...need to replace the JIC Magic SF1s that came with my SC300. Insurance will be replacing, but I know the SF1s are discontinued - what would be the current equivalent from JIC magic (or anyone else
