We like the RS3 out here because it handles the heat of our tracks. Nothing wrong with the RE-11 and people in colder climates seem to prefer it. Never used it personally, but on tires I sort of follow the herd and my herd picks RS3's in SoCal.

On the OEM suspension, I personally feel(don't know) that the Hotchkiss would be too much. I would suggest either the Stillen or the Eibach sways as a huge, but not overkill solution that are both fairly inexpensive, and will make a large difference. I am now running the stillen sways on OEM suspension(non nismo) and it is wonderful as far as I am concerned. I can tell that once I upgrade springs and dampers that it will be too soft, but it is still an enormous upgrade from oem for ~ 300 bucks.

Here is another bit... If you dont have adjustable front arms... You will need BAR.

There isnt a lot of grip on the sidewall of any tire.
Just sayin.

Sticking with our super laps. At least for now, not going to drop down to 18s so closest to "square" setup will be to run the 275/35/19s up front.

Currently on PSS and happy with them so far. If wife wants stickier tires I will def look at the rs3s

Are you suggesting keeping the stock rear bar and upgrading the front to the stillen or eibach set full stiff I'm assuming?

The outside blocks on the drivers side front tire are toast after Roebling. Very outside edge is just worn completely.

Run the front of either brand at full stiff, with the eibach(don't know for sure maybe medium on the rear), on the stillen stay softest in in the rear.

The point is that both at full stiff are very close to about as stiff as you can go on OEM setup. Any stiffer(Whiteline or Hotchkiss or Doran's professional bar) is probably too much for oem dampers and springs. It's all about balance and is all relative.

It's like asking if an Olympic boxer is too tough to fight your little brother(OEM) or if an Olympic boxer is tough enough to fight Pacquiao(racing suspension).

worth downgrading to 18's just because of saving the $$ on tires alone, for example rs3's in 18's my hook up is under $900 but a set of 19's it's close to 1200. So after about 4 set of tires your savings is exactly 1 set of nt03 enkei 18x.5 wheels.

That makes sense. what about with swift spec R springs which I'll be going to down the road. Would the stillen bar be enough or would I need to upgrade to whitrline or Hotchkis at that point?

Spec r's are a mild but very good upgrade as well. You are still within the OEM spec, but probably will want to upgrade your dampers to Koni yellows. Again another huge but very affordable upgrade in the street/track range. If you are going to look at swifts+konis, then you should definitely consider the KW one way setup as well. Both are very good in that price range. It sort of comes down to preference at that point. KW has some advantages in that the fronts are ride height adjustable coils which help with corner balancing, but me personally I hate the damn colors of their stupid springs so would buy the Swifts and Konis lol.

I priced the square 18 set up compared to my current 19 setup and it's no cheaper really on tire rack. Going to 275/35/19 up front might change that but I don't have a "hook up" on tires so I'm paying retail.

At this point even though I know 18 are "better" for the track I'm not going that way yet.

Lol at hating the colors

I'll most likely go with the swift/Koni yellow combo as it's a set it and forget setup.

Goal with this car is to keep things simple even tho I get that we're leaving handling on the table so to speak it will still be a big improvement over stock

Yeah I didn't even understand why martin liked the damn KW, and he didn't understand why I hated it, and then I told him it's the colors, and then he said "Lakers Bro". And then it made sense to me.

18's are the way to go for affordability in tires. The price is honestly 100's of dollars difference as martin pointed out and there are many more options with a 18" wheel. It also improves your acceleration as the drag strip guys know. I run 19" Foose "Bling Chrome" wheels on street 1 because they look nice, but 2 I would be at a disadvantage on track. If you want to see the real problem browse the GTR forums where they all have 20" wheels. There are no tire options for those guys besides the toyo R888. They have one friggin tire option in that size. (maybe soon they will have the NT01)

With an 18" wheels your tire options are 10 fold at least.

And yes, if you were potentially in need of tires, then talking to the owner of a car that one of hankook's sponsored drivers on this forum owns is mutually a good idea.

Yeah I had that problem for a while too, I'd just destroy the outsides of the front tires while leaving the inner tread looking new. More front camber! (and caster if you can)

Thats the truth. Im loving my SPL front arms! No specific race slick setup tips for us (spring rates used, bar sizes, alignment settings?)
