Update
Due to post by TempeST and Taylor at BC I decided to go up to 8/7k on the spring rates
------------------
I am running the BC's with the 2Jr race spec 6/5k BC springs now and it works really well but the ride on 15's is so good I can go up a notch and the Swift springs are more linear than the BC's and might ride about the same. I would love to try even stiffer springs, as high as 9/8, 10/9, or some wider spread front to rear but at $340 a set I am playing it safe for now at least and the valving will work fine.
The reason for the change is to reduce a bit of body roll and just have a better working coilover/spring setup.
I prefer to control as much body roll with springs as I can live with the ride on the street and still maintain good tire contact on bumpy roads and use sway bars as little as possible, fine tuning instead of the normal major body roll most use them for.
I base my ideas on this from studying race car engineering books over the many years of doing this stuff.
Another benefit is their is little if any weight gain compared to bolting on parts I might not have to use.
I will post pics when I get the parts and install them.
For now I have only been running a stock ST front bar with stiffer bushings and no rear bar. Due to the rear camber change I cannot use others exact setup as my car will react quite differently, as planned.
I do have a 5-way highly DIY modded GC BWM rear sway bar I will test with later on and I am considering installing the none ST front bar when I drop the subframe to install the aluminum steering rack bushings.
I expect to have a set of BC 6/5k springs to sell in the next few weeks, they still ride great, almost to good on my 15's in case somebody with the softer normal 5/4k wants to step up a bit. If the new 7/6k setup is still a bit softer than I want to run I would order the next level up and sell them as well. I am retired, no shop, little time to work on the car, funds from selling stuff needed to do upgrades, etc.....but this works out as it helps others do upgrades for less cost when I sell stuff
--------
Why stick with the BC coilovers?
Because I have used them on other cars and now on this one, very cost effective, quality, value, performance, support and they were the only thing I could get when I started this car project and I see no need to change them at least for now.
I have had low to top brands all the way up to Moton and an $8500 custom set of Ohlins on other projects, I no longer have that kind of money, really never did I just spent to much, and I am happy with BC for this car. At some point I might try some Club Sports I think it is KW but not for now am happy with the BC but if an under $3k set of Ohlins was available I would likely go that route over any other, they are amazing.
