Question about adjusting front coilovers

I've got Koni Reds and 250# springs up front right now. I've just installed them and I moved the perch as far up as I could by hand but I want the front end a little higher. The springs are 12' 250's and the spring starts to compress which makes it to where I can't turn the lower perch by hand. Is it fine to crank the lower perch up with the spanner wrench to where I want it or will this cause too much preload. Prior to the 12" spring, I had always used 10" springs and hadn't really ran into this.

Yes, it's fine. I'd spray a little bit of light lube on the threads first.

Ok, thanks. Just wanted to be sure, I didn't want it to be spring loaded or anything.

The spring is loaded whenever the car is resting on its tires.

Koni reds? Didn't you have SA's or DA's on that thing? You seem to be de-modding and re-modding with lesser parts.

250 lb/in is pretty soft for the front. Maybe he just wants a cushier ride!

Probably. My Grandpa seems to like those rates on his Town Car. (j/k!!!)

LOL

You keep bashing fillings with those high spring rates and I'll be riding Cadillac style.

I've still got the yellows for when I go to the ta/phb combo. Until then, its boulevardpimpin. And, BTW, 250s have a higher wheel rate than hr race FWIW

Yea, but you're hardcore....you got rep-re-zent. 350-ish rate isn't that bad, Mr. Hank Hill.

I would've kept the Yellows on there with the 250# springs. My first coil-over setup was Koni Reds with 300# springs and it was horribly underdamped - ride quality was terrible. Hopefully you won't have the same issue with the slightly softer springs.

'89 GT convertible, N/A 357W, MM front susp w/425# coil-overs and Koni D/As, MM TA/PB rear setup (Koni Yellows, 390-430# springs), Stoptech 332mm / 12" Baers, MM 6 point rollbar, Maier 1.5" flared fenders & quarters, 18x9.5" front/18x10.5" rear Enkei RPF-1s (street), 18x10" CCW C-10s (track), etc...

I wonder if you had a bad set. The reds overlap the single yellows which mm says starts at 275 springs. Seems that the reds are similar to hds in their rebound valving as far as suitable spring rates go.
