305 square on 19x11

Went to SCCA TX time trail event yesterday at ECR. Trying out some v730, 305 square definitely helps with corner entry rotation a lot.
Doesn’t feel much faster than PS4S star spec. But it’s cheap and last long , good practice tire!

What offset and spacers are you running?
I'm trying to find this setup without spacers.

Curious about this (and suspension) setup as well.

Different setup but apex 19x11 square with 305 Goodyear 3r (12mm rear spacer and 15mm front spacer ). Need at least -3.3 front camber for it to clear. No rubbing otherwise

Do they just not have an offset that would work without spacers?
I feel like if I'm gonna buy spacers I'll just keep the stock wheels

Pretty sure the Titan wheels from PHD Racing don’t require spacers due to the lower offset.

Mine is 19x11 +8, also getting set of 18x11 +9. Both would work with no spacers. Personally I don’t like using spacers, less unsprung weight is always better

Stock suspension, if you don’t wanna use camber plate, get this fender clearance kit. No rubbing

NekoRacing shouldn’t a 18” wheel go up to 40 profile sidewall? OEM the 19” wheel is 35 profile (with the rears 20” being a 30 profile).

Depends on the manufacturer, this wheel manufacturer made sure it will clear stock calipers with their barrel. I’ll keep you updated

Yes, 275/40-20 would be the ideal size for track matching stock sidewall thickness. Both the GT4 and M2 Racing will use 300/40-20 slicks. But most track guys and I’ve been running 305/30-19, it’s a very popular tire size with a lot of options. Downsizing thickness is not a big problem to TC as long as front and rear keep the same ratio. Some people prefer the corner turn in feeling of smaller sidewalls ,the car feels more responsive. But I’m giving 295/35-18 a try to see if I like how it feels.

Ah ok got ya: so no worry about overall OD being different. Simply going for track setup/feel of the car and what tire options are available. I was assuming the constraint of keeping final OD the same as OEM spec tire as the design constraint.

Don’t worry about overall OD being a little different, that’s one of the easiest way track people modify their final drive according to different track preferences (acceleration/top speed of each gear). As long as front and rear is the same ratio, you’re good to go!

Did you use camber plates for that setup? If not are you running the modified wheel well liners?

I've basically used up the stock rear Pirellis that came with my car and now want to go to a 19" square setup....but since I only track 2-3 times a year not sure I want to be DD'ing with -3.3 camber!

You’ll absolutely need camber for fitting 11s up front. Tested with friends with different wheel offsets. If you don’t want a lot of camber stick to a 10” wide up front

Thanks. Absolutely love what you've done to your car Leggo. Just did a bunch of searching and reading up and yes, figure I will stick with 10s up front. In addition running 275 winter tires half the year really wouldn't be smart with camber plates (I know they're adjustable, but have to draw a line)....305s should fit out back no issues though correct (20x11" Apex, 4 mm less offset than you, guess I could just go 19x11 as well, the 20 is a bit rough)?

For the couple times a year I make it to the track, I'd honestly be happy with a golf cart and seeing if I can improve my times lap after lap, for me its the technique and don't need to be compromising the car for its intended purpose...a daily, that occasionally goes to the track.
