I've  been kindaq following this thread from the
beggining. 
& since you'r  a trusted, very knowlegable person Scott
I'de like to know your opinion on  my setup.

91 v8 5spd. 2Benn front & rear coilovers.
Front  springs are (L)9-380(rate),
& rears are (L)7-400(rate)
Got the  bigger 28mm front 4.2 bar & got the RSB from a
95.5 S6A.
I run  255/35 18 tire on BBS LM 18x8.5. I'm looking for
a bigger  tire...265'ish/40.
But the rims are 35et & I'll be running a 5mm  spacer
up front & none on the rear
In your expert opinion...what you  think about that?

Ron:
I tried a long time to get those 2B front coil overs to work well in a C4  
chassis (type 44 Evo?).  As in the customer that insisted on them (against  my 
advice) spent a lot of money having me try to get them dialed in.  For 2  days, 
I moved perches, changed shocks, adjusted konis, changed settings, and  
finally gave back what I considered best.  3 weeks later we pulled it out  and put 
the stock uprights back in (can't remember who's springs we used  tho).  The 
rears are about right in terms of rate, but if possible I'd use  a 10in spring 
in the back myself.
 
Rear bar probably isn't doing much, just make sure it's not limiting rear  
wheel travel (or front inside wheel travel).
 
Tires, I run a 255/40 17 on 17x8.5 and find that about the max that the v8  
handles very well.  The problem I find with 18's are potholes, weight, and  
energy in the sidewall.  Much more than 17's I find the slop in the  suspension 
too much and the car really tramlines around.  
 
Summary, sounds low to me.  Not sure what your target is in terms of  
performance, but I see issues with reduced rear wheel travel, tramlining front,  slow 
acceleration from tire weight.  From an investment standpoint, I'd  probably 
start by putting in the longest rear spring your ride height allows,  and make 
sure you maintain the F/R rake angle of a stock v8
