Sizing help on buying new set of wheels
 

Currently, i have some Enkis T6S 18x8 wrapped on some Pilot sports 4s for summer setup. Idk what the weight is on that wheel and size combo, but the car drives fine on the street and on track with that set up.

Im planing on buying Gramlights 57xtreme 18x9.5 with the pilot sports 4s.

Since Gramlights wheels are wider, they should weight a bit more than my enkies. My question is would i feel the different when driving on this bigger set up? Or gramlights are 'lighter' than usual and i can get away with the weight

Although the car is on stage 2+ and it feels better than stock, i don't want to make this car slower than it already is.

Based on a few quick searches, the enkei t6s that you currently have weigh about 21.5lbs/wheel whereas the gramlights would weigh about 21lbs/wheel.

So if the tire size is going to be the same, then they should feel pretty much the same.

What size tires are you planning on using

Yea looks like the weight is very similar, just wondering if im going to feel any downside with a wider wheel/tire

Pilot Sport 4 S 245/40ZR18

Yes the inertia will be higher. Wether you’ll feel the difference or not is debatable, hard to say without trying it since not everyone is as sensitive to it.

I reckon the 245/40 tyres (and associated increase in rolling diameter over stock) would make more difference to the feel of the car than the wheel change. 40 profile is far too big, that’s over 12mm gain in ride height. 245/35 is near identical to stock, 255/35 is slightly larger, but still much closer than 245/40.

Depending on offset you may need spacers in the front

Maybe i should reconsider and go with 17x9 gramlights instead. I like how the 18x9.5 looks, but knowing that i track the car maybe i should stay with a smaller / lighter wheel.

If you track then yes 17x9 is the way to go and they will weigh less than the 18x9.5 wheels. Not mention "Gramlights" really aren't even all that "light weight". Look into Konig wheels their FlowFormed wheels are a good price, just a suggestion.

What do you guys think about pilot sorts 4 all season tire? Currently I swap wheel/tire set for summer and winter and been considering having just 1 set as i dont drive the car much.

Any experience with that tire on track/sprinted drives?

If weight is your concern, try looking at WedsSport TC105X. For 18x8.5 +43, it only weighs 16.42 lbs!

Is +25 mm the biggest we can go in front with stock wheels and tires? Is there a list on max negative offset for different size wheels?
