Spring question for "AGood2.8"
who made your spring in your camaro? are they custom V8 springs, GW springs, or generic AFCOs?
I'm looking for ~800 lb/in linear rate springs.
What difference did the baer bumpstear kit make?

They have been on the car now for at least 10 years- I know I tried about 3 different combos up front before I settle on this- had a friend back then who owned a spring rate tester and I d remember testing them before being trimmed to ride height at just above 800lbs. I think these were an lowered Iroc sport/race spring (maybe Suspension Techniques- they were popular then)but I'm not certain which one I have (sorry I have done so much work to so many vehicles of mine and family that its hard to remember exactly.) I've always had many different sets of spring combos laying around from different GM applications over the years- Sorry.
The Baer bumpsteer kit did make a difference when I have the car loaded with wife, kid, and baggage that goes along with them on every little journey
. Even before I installed them, I never had bumpsteer because of the front end stiffness unless driving with passengers. Now with passengers its not noticable any more.
You need a good alignment shop- a buddy of mine Jon owns Accurate Alignment very close to DynoDon's shop in Orange(on batavia just N. off Collins). His kid brother Chris will work with you and set the car to your specks If you need guys that are race friendly.
Edit: I assume you realize from my call name that this car is not a V8 either- Just a lightweight little 60*v6 with those rates- aprox 800#F & aprox 225#R and Koni yellows with rebound maxed out to dampen them.

now that I have time to add more to my response
, I have a few more Q's for you.
From my research it seems that 800# front springs (at least for V8's anyways) seem to be a good starting point for the front springs but for the rears it seems 150#-175# as compared to your 225. But that may be due to driving style, preference, etc. Are the 800# front springs bone jarring or pretty brutal on the street or are they pretty docile when complimented with your other suspension upgrades? I presume this is your daily driver car so I guess it couldn't be too brutal if the wife is willing to pack the kids in as well and go for a drive, right?
thanks.

It certainly is more comfortable when we are all in the car. I like things stiff and the wife doesn't drive far ( actually she rarely goes on the freeway) alot of short trips for her. {Edit: dont know if I have noted, but the wife likes and uses this car as her daily driver}
I will drive it occationaly on the freeway but mostly with all three of us in it usially heading from Orange up to Covina Hills. It rides very nice at higher freeway speeds but would certainly get old driving this car to Vegas or such.
Its the most fun for me when I'm by myself in it- Thats when its most rigid of course. My driving/ racing style has always been stiff springs and small rear bar to muscle a car through a corner with tons of throttle to set the chassis and to also get you out of trouble even at 80 mph ( I have witnesses that will attest to me "sprint carring" my Vette around the entire 2nd half of the 91E to 55S transition at 80+ just because it can). This car does not have that kind of raw power- not even close- So I have learned to chage my driving style only when in it to drive more like and open wheel car and not like a full bodied road car that can attack corners over aggressively.
Its not as fun to drive true lines- but the g's are incredible in this thing. I can get away with stiffer rear springs and bars in the rear than the V8's in ratio to the fronts because of my weight bias and lack of power- you do the same exact setup on a V8 and the tail end will be way loose.
I think you can get away with 200 or 225# rear springs with 800 fronts on a V8 but keep your rear bar down to at least a 21mm or maybe even smaller. I run 34 solid front/ 25mm solid rear is best on smooth- 23mm best on bumpy
