In an ideal world I could also flush up the wheels a bit AND have the drop without really losing the changing how it handles/slides...

The question is what's the magic formula?

It's not as simple as keeping the same ratio as stock. The front and rear of the car react differently to changes in spring rate due to one end being a MacStrut and the other being a multilink.

I suppose the shortening of the spring, thus affecting suspension geometry, doesn't help with making it easier either.

I've been reading up on dampers lately (and have a crapload more reading up to do still) but I wanted to post up some good links/info here in one place. Feel free to add to this list, or if there's something that contains bad info, let me know (prove it though!) and I'll remove it. Some of these links (most maybe?) have already been posted on here but they are all over the place..

List:
Basic damper tuning suggestions by Ford/Sachs
Penske's Adjustable Damper manual/tuning guide - MUST READ IMO
Reading Shock Dynos (at least some material copied from Penske's guide, I haven't read it but some pictures at least are the same)
Far North Racing - General Shock Info
Far North Racing - Shock Buyers Guide
Far North Racing - Setting Shock Forces
Far North Racing - Reading Shock Dynos
Far North Racing - Shock Tuning Payoffs

Far North Racing has other good info on their site also.

The Penske manual is awesome.

Thanks for the links, Dave!

That Penske guide is phenomenal. Comprehensive, yet well focused on the "important" stuff. I liked how they explain the behavior in each quadrant of the dyno chart (wouldn't have been 100% intuitive).

Today, the internet has proven itself useful for more than just cats and porn.

When you buy a new car you will more than likely be offered the opportunity to purchase an extended warranty, which is intended to protect you over and above the manufacturer’s warranty.

How does this have anything to do with this the topic of this thread??? I'm confused...didn't see anyone mention warranties. Think you might have posted to the wrong thread!

This post kinda just touched on motion ratio and that's it. I'll try to make something a little more detailed soon that talks about choosing exactly how firm your springs should be.

Ahh the joy of being in mechanical physics is that now i can actually do some of this math. Always fun to start applying what youre learning in school to what you really want to do in life, kind of a game changer.

I'm curious if RCE has done any R&D on the 2015 FRS? Reports seem to point to the 2015 FRS as having revised springs & dampers. I had a 2013 and moved to a 2015 and am quite happy with how the 2015 feels even compared to the 2013. I want to lower my 2015 but it would suck to change negatively in anyway how it handles...because it's amazing!
