My quick search, Megan 12/8 and the BC is 12/10. To soft up front or rear?

Some discussion here: https://www.clublexus.com/forums/sus...ring-rate.html

If one is accustomed to the IS-F than yeah, this is going to feel like your couch let alone the stock springs.

Ok so the LPs and EZs have the same spring rates. Both have the ishue in the rear. Other than more dampening levels on the LPs with the same stiffness. Why should I buy the LPs over the EZs? Also, I'm lost on the whole drooping springs or dropping the preloads...

Sorry, but the rears maxed out with a 3-4 1/2" gap between the threads and a 2 finger gap isn't low enough for me. I got my info from a fellow member here who also has a 98-00 and had LP's. He eventually switched them out for D2 coilovers, but now he's on PBM's. Guess who!

Yes, LP and EZ has same exact spring rates. From what I am hearing, EZ has issue in the rear, LP has issue in the front. I can confirm this because I have EZ's and they have the issue in the rear and my buddy had LP's and he had the issue in the front.

Drooping the springs and dropping the preloads is essentially performing the same task which is basically letting the springs hang to go lower since the coils are already maxed out. You do this by unlocking the top 2 collars and lowering the whole spring perch down. Megan states to not droop over 3cm, but I've done 4cm and it's fine. Doing this will compromise shock travel and the rears will become more soft of course.

Not to mention if you are or want to be slammed, you're going to bottom out everywhere even with the max stiffness. I experience this everyday . You really do get what you paid for in the automotive industry.

Not trying to stray people away from Megan products, but I simply got the EZ's cause I'm on a tight budget. If I had money to shell out, I'd get PBM's. But then again, it really depends what your daily applications are.

I'm on a tight budget also. Id much rather have a forward rake then a reverse rake. Idealy would be no rake at all. I like to ride low, but I also like halling *** around corners. I can play with tire sizes to close the gap in the rear and use a lip & side skirts to give the visual aperance of being rilly low.

On the ls and gs, youre more likely to see a reverse rake aka boated because the rear fenders are alot lower than the front fenders. If the gap between the front and rear fenders are the same, you will notice the overall car will already be raked. Most people dump the rears lower than the fronts to even out the rake.

possible that they were swapped, front to back between you two? i think megans all use the same shock cartridge length, and it's just the mounts and spring rates that differ from front to rear.

iirc, the LP's are the opposite of the EZ's. fronts can't slam but rears can. either way, the solution to this would be to drop the preloads. or you can avoid that by getting other coils beside megans.



^that's with 4cm of droop of the springs in the rear.
Sounds like a formula to mix them. Then as Vincent mentioned in the other thread, buy coils that drop more already.

So effectively, how much drop was achievable without adjusting the preload?

Having this info for the Megan EZ, LP, BC, D2 is good info for the suspension section of the FAQ. (This all varies with wheels/tires but as a rough indicator what we can expect is good. )

this is the rear maxed out (not messing with the preloads) on a 35 series tire on an 18" wheel just for reference. if you went with a 40 series, that's a 1 finger gap, which still isn't low for some people.

impossible for me since i double checked the spring rates before installing the coils onto the car. 12k f / 8k r .

Hmm.. if I could find someone looking for coils but not looking to go super low, id go halfs with em to buy both LPs and EZs and I'd take the EZ fronts and LP rears. Other person lot looking to go as low as what I plan on would get the LP fronts and EZ rears.

Nah its your tire size. It would make sense that you'd be barely tucking on 45 series cause i stated previously that a 35 series is 2 finger gap, 40 series is 1 finger gap, 45 series is no gap/barely tucking.
