Offset Issue?

Hello All!

I picked up some new wheels for my 997.1 base Carrera. The wheel specs are 19x8.5 +41 mm offset and 19x11 +50 mm offset. The tires are PS4S 235/35/19 and 295/30/19. I think the fronts stick out a tad more than I like. Would any of you know if this would be an issue with form, fit or function at my stock oem ride height. I'm concerned about any rubbing or interference during hard cornering.

Since the front sticks out from the +41 offset, is it definitely a no go for lowering? If I can lower what is the most I can go?

This vehicle will be used as daily and a few autox a year. I attached some pics for reference.

Thanks in advance!

Regards,
Swiss

Nice wheels and looks like a perfect lowering project. To me, the offsets don't look bad at all but lowering it will tuck the wheels just a bit further into the well which may make you happier. Will also improve the overall stance imo. I'm a die hard H&R springs fan for lowering which drops it about 1.25". Your base 997 should easily handle that as it sits taller than the S. I've had no problems lowering S cars with H&R's. If you still don't want to go that low go with Techart or Eibach. Either one will drop it about 1" even. Or if you're itching to spend more money, go with some quality brand of coilovers and adjust the drop to your taste.

I'm not sure who advised you on those offsets for a NB car but they're not a good fit. I've done multiple posts here and on Rennlist regarding NB wheel offsets with photos of different ones and what to avoid for a NB car. On an 8.5" wheel an et50 is perfect (vs your 41) and on the rear, running a 12" wide wheel, 68-74 is perfect.

This is what an 8.5" et 42 looked like on my car and I pulled them off after 1,200 miles. My car is also on coilovers and slightly lowered. The car had high-speed stability issues with these offsets becoming very darty vs the rock-solid feel it had prior. Tire make, model, sizes, and pressures were exactly the same with the wheels that had these offsets and the proper offsets with the only variable being the offsets.





When I had my current custom Forgelines made, I used the offsets I mention above and the car drives perfectly. If you decide to return these wheels I have a similar spoke design to your Forgestars on a set of fully forged, lightweight Champion RS171s that were fully polished then clear powdercoated for sale in the Marketplace, that will look and drive correctly on your car. The Champions look like this.

+40 offset

Unless you are not going to lower it, +41 will poke out. You will be fine with H&Rs as it drops more than the Eibachs with your offset. I have 9x19 et40 and 11x19 et40 on Eibachs and it pokes out even if I am using thinner tires 235/35 with bit of stretch. I'm doing coil overs this week to make it flush upfront. On stock height, +50 to +53 upfront is the ideal offset and about +50 on rears.
