thanks for that informative post! Most important thing is the car feels neutral and safe....:smile:
As you well know it's a combination of other things as well such as sway bars, rake, ride height, tires, etc, etc...
Currently I'm running the trophy sway bar upfront and the Zinardi bar in the rear. Have CT front camber bushings installed as well and set at 2.5 negative in front and 2.25 the rear. Tires are wearing even and tire temps are right at 200 across the board. Ride height is set higher than most to clear the 275x35x18 and 315x30x18's I'm running. 5-1/4". Right now my rake is at 1/4 inch, which I'm about to lower to 1/8" on Billy's continuing advise. Also running NT-01's.
I have tried the 457/457 they came with. Front end was too weak, I was killing my front fenders and I hate oversteer .Tried 557/457, front end was still too weak for my liking. Changed to 657/457. This balanced the car out very well. I moved up to 857/457 and the front end felt numb and started to push too much. Went through a series of Sway Bar adjustments, Compression and Rebound adjustments but still didn't like the way it felt. I dropped back down to 657/457 for the time being and it became neutral again and very well balanced. I may try 757/457 here soon. Have the 757's sitting here, just haven't put them on yet.
I running 2 clicks from full stiff on the front and 4 on the rear for compression and Rebound is set at 3 front and 5 rear at this point.
As Billy has explained to me.
More rebound = less roll, quicker response, but less grip.
More compression = better response, bumpier.
So at this point I'm just concentrating on Compression, Rebound, Rake and Tire Pressures getting them to all work together.
Have the last NASA-AZ event of the season coming up and I'm leading the UMS TA unlimited class by 35 points with the last event being a double points event so now is not the time to experiment again or try and fix something thats working.
Best lap times so far for me have been the 657/457 combination by over 2 seconds over anything else I've tried so far on the 6 tracks I've been on with the KW's this year.
We all feel something different with our individual style of driving, so what works for me may not work for someone else, as you also know
I run 757/517.
Its a compromise track/street.
Its quite a bit stiffer than your running now at 357/357.
Takes other suspension pieces to make this work.
Is the rest of your suspension stock ?
OK....
Depends on your power output. I run the 517's on the rear now so the car doesn't squat as much under acceleration. I was running 657/457 before changing to 757/517. I'm also putting 565 hp to the rear wheels.
I gave Nick Frenzi my 657's. Nick had the same situation going on as you do and jumped up to 657's on the front and left the 357's on the rear and loves it.
I'll see if he will jump in and give you his impression for his set up.
Guys I just need to vouch for Coz here. He has been very helpful as my go to man for KW customer support. I installed the v3 this weekend and am thrilled with them so far- I used Billy's recommendations for the settings and they were very similar to my type R suspension which is what I wanted to achieve. It was a tad bouncy so I backed off the front compression/rebound two clicks quickly thereafter as I used 457/357 springs instead of factory. Now being able to fine tune these to your liking is great too, and you learn a lot and can change your car from street to track in a snap.
+1 for Coz.
They don't make them like they use to. Coz that is. Not the suspension systems
