Serious Track Setup
I was a new driver two years ago and have been adding suspension part mods over this time. I was very happy with the EVO camber arms . I have just gone to 700 lb T2 springs and WOW what an improvement. 4seconds faster at Thunderhill. High speed turns I was 20mph faster and one gear up.The body movement was eleminated. This instability was very unsettling on high speed turns. The car is now very stable for both slow and fast turns. I am a real happy camper. I also use this as my daily driver and tow a trailer to the track with my gear. It is very firm around town with the many patches in the pavement but I drove up from San Carlos to Thunderhill and found it fine for freeway driving. I would reccomend this setup to any serious track guy.
350EVO sways,links, chamber arms and torsion bars, Koni SA shocks full stiff, and the T2 springs. Camber set -3.0 front, -2.5 rear

Well, even EVO350 doesn't call the part what it it is. EVO sell's it as a lower control arm, that's the part he's talking about. The FSM defines is correctly as a radius rod. Other's sell it as a traction arm or as a adjustable toe arm.

Std Sa Konis
I am running the shocks full stiff. I am also running the sway bars at mid. this gives me best balance. This is in combination with 17" wheels and 275x40 x17 Kuhmo tires

Your camber set up is definite for race purpose only. That is a little too much camber for everyday driving. Unless you take every turn hard (like most of us here 
) you are going to put a little extra wear on your inside tire traction. Of course you probably already knew that.

Still a daily driver but low milage
Yes the wear is a problem. I remount my tires to streatch the distance but I only drive 4 miles to work. This car is drifting to a deticated track car in the next year or so. Tire milage is not an issue with me.

are there some readily available linear springs a bit less hardcore than the T2 springs?
625/700 equals 11.2kg/mm - 12.5kg/mm = pretty much undriveable on the steets were I live.

Their is a way to convert the Koni shocks into coilovers and run your choice of linear spring, something that I'm still ironing out the bugs on, glad I did not opt for 9Kg rates.

They performed the best on the larger tracks. But they were very capable on the smaller ones too. I've run over rumble strips at Road America, come into Gingerman's 5 & 6 completely sideways on the ABS, gone into a 4 wheel drift entering the boot at Watkins Glen and everything in between and the handling recieved my inputs without hesitation or becoming unsettled.
I don't think they would hold a candle to the T2's here, but for the money, and excellent performer. The smoother you are the better they perform, but they are relatively forgiving even for a noob. If I was going to continue to track the Z, I would probably drop the rear spring rate about 50lbs.

Nano, I occassionally take my T2 racecar on the street for quick trips to 7-11 or Starbucks (I left the cupholder in) and with shocks that are corrrectly valved for the T2 springs, the car rides better than it did on the OEM springs/shocks! The key is to get a shock that is valved for the spring. Dont know where you are driving but here in Seattle we have some of the worst roads, the only states that I have seen worse road conditions were in PA and NJ.

dnguyent,
we use JRZ double adjustable.
http://www.theracersgroup.com/parts/...cks/shocks.htm
The shocks we currently use do not have the remote resevoir otherwise they are exactly the same as the ones in the link above

I'm just trying to learn as much as I can about these higher end setups since I may pull the trigger in a year or two. I can justify a heavier investment in the suspension by leaving the engine completely stock.
BTW, has anyone fitted up the Motons that 350evo sells? I can't tell whether it's $5700 per set of four or each, and am a bit embarrassed by this naivity...
