Nice, I love mine. I run mine rather soft for the street. 6/6 up front and 3/3 in the back for the street. Depending on the course I will go from roughly 10/14 up to 16/16 in the front and 14/18 up to 20/24 in the rear for the autocross days. I have quite a few notes from each event that I have run on different combinations. I am running -1.5* and -1* for camber.

Cool, may try the 6/6 3/3 again, just seemed to loose and not as controlled over bumps. My cambor is -1.2 and -.7.
So your running more bound then rebound it appears for the track?
trying that some now for the street so isnt so firm, seems opposite of all I have researched though.

I read these articles to help with how I like the car to feel. When it comes to setting the car up it is all on personal preference. Most of the courses I have ran were mostly smooth with only a couple major bumps in the course which allows me to keep the rebound at a higher rate. Again, it is all subjective to how you like the car to feel. For the street the settings I use don't give me the most control but it keeps the ride soft, especially for passengers. I don't mind keeping the shocks turned up most people that ride with me don't like it.

Thanks. I saw some of those. Yeah courses we do are smooth also, fontana is but rough and chews tires a bit but no bumps.I do like the control of the 8 to 12 range on the street, though at say 9/12 ratio back is always more firm and bouncy, but of course the car turns faster and is more fun at low speeds.front/back the same ride is balanced as the
car is 52/48 balance itself.Right now for our bumpy rippled roads a balanced f/r works best for me and have it at 8/5 front and rear, keeping bound the same always f/r and tailoring rebound at about 1/3 stiffer then the bound

Off topic, VR, How much lighter are your wheels over stock and how have they held up?

about 6-7 lbs lighter each, and thats 9's and 10's vs 8's and 9's. Was vary noticable on a bad section of freeway and improved the ride. Havent been able to tell in auto x, been changing to many things..lol
So far holding up fine, a few mars in the clearcoat from cones and mounting the new tires at the extreme edge of the rim where it meets the tire but thats it.

OK- I'm a spec nerd, but the stock 20X8 fronts go 32lbs, TSW lists the Nurburg's 20X9 at 23.3lbs= 8.7lbs or a 27% weight reduction.

Stock back 20X9's are 36lbs, down to 24.45 for a 20X10 TSW= 11.55lbs or 32% less.

IOW- they not only look good, they make a difference!

Cool, Better then I read somewhere. Or just forgot the numbers...lol

Personally I like the looks of the OEM wheels. So much that I just can't bring myself to drop $1k+ on a set of wheels. They are extremely heavy pigs though. Every time I have to lift one up to put on the car I'm reminded of that.

Eventually I may have to break down and buy some wheels but I always seem to find something else to spend that money on.

They are nice but to heavy.I noticed a difference in ride on bad freeway sections and bad roads. These sizes are a dual mode. Stock size tires fit as do the larger ones I have now and like the look, a win, win!

I edited post 14 with more findings.Going to write a book..lol

Latest update. Tried 6F3R like Pedders says is a start place for street oem for the regular XA's.Didnt like it at first, again, and what alot of people with xa'a said, still that rear end bounce and firmess, like the tires were overinflated. Same result as when there is more rear rebound vs the front, but not as bad. Well today put the tires at 35/35 psi, they were 35/33, the old less air in the rear makes softer ride theory.Well not this time, the 315 invos on 10" rims, and invos in general seem to like more air, and that did the trick! 2 lousy psi with my setup and tires, got rid of the rear bounce its pretty compliant over that patched pavement, stable, softer yet solid and firm all at one time, a little firm gjiggle here and there but with this setup to be expected.On the freeway nice and composed, solid and stable and takes the drops in the concrete sections well and controlled, you bounce up a bit in the seat but my head didnt hit the roof this time..lol.

Anyway great shocks and can adjust till the cows come home to whatever you haveas a setup and your roads, what you like as to ride feel and all that.

Any more info and you can find it in my new book to be released in a year named " The joy of adjusting shocks"...lol

Played with more settings. I like 12/10 and 12/10 as another street option. Firm but balanced and soaks up bumps. Better then the 9/6 setting and like it better then the 6/3 comfy setting, though that one is best for really bad roads. These parts will always be firm though unless you go 0/0 but thats not that controlled.
12/12 is good but firm, 14/14 is factory stock but a bit firm, though all these settings are pretty balanced as settings same front and rear

[VR Baron]

Latest tests and 9/8 & 9/8 works really well on the street. Think they will stay there for now.One click softer in the rear and you start to notice it, good, but a little softer.One click more then the front and it is more firm,my butt dyno has become well calibrated by now...lol I like the balanced settings vs the others, again as the car is about 50/50 balance also.Note rebound 10%more then bound is good and I have read recommended as best combo, other then if trying for more or less understeer then up that ends rebound.
One last bit, 1275 miles and coilovers havent settled one bit, like that, will see if they do later.
Well thats all. Merry Christmas and Happy holidays to all!!
