Default Stew's Bagged and Boosted IS350 on Forgeline Wheels

Forgeline Motorsports. Welcome them to the scene.

First off, I don't work for, nor am I in any way affiliated with Forgeline, but as I was on my quest for 3pc wheels, I decided to choose a smaller company right in my backyard. Where instead of being like most, 8 weeks later and have no idea whats going on, I could drive 45min and figure out exactly where my hard-earned money was going.

My first trip to Dayton, OH to visit the shop, I was greeted by the owner himself. I was taken on a tour of the facilities, and then my car was put up on the lift, and measured to the mm, plus a lot more, to get the exact specs I wanted. He even worked with me on details such as achieving maximum lip on the rear, while leaving tolerance to shave down in front and still clear the brakes if I chose offsets that were too aggressive.

3 weeks later, yes THREE (not 6, not 8), I made my return trip to Dayton to mount up my wheels. The entire factory gathered around my car for this one. Mind you, this company contracts with racing divisions, and built the wheels for the Hennessey Venom GT world record speed run. As such, the faces looked much like this:



While me and my buddies from Lowcally Famous are just running around like:




So anyway, without further adieu:

Forgeline GA3 w/ exposed hardware in Midnight silver with polished lip. 19x9.5, 19x11.5.
As far as offsets, the question one should ask is if they even HAVE offsets.

Well, I'm assuming that they don't have a lot of expertise in planning for camber angles. That work was done in my garage with lots of spacers, an old wheel, a 6 pack, and lots of hours. Once I knew what I wanted, they let me know how much backspacing I had to work with. Then, I had to make touch decisions on tire size.

I went with a 265/30 on a 11.5 over a 275/30 on a 12 simply because the former gives max safe stretch for clearance purpose, and minimal tire height for looks (overall ride height), and to utilize the cars HP and TQ curves to the max for street purposes. Even then, I'm running them at 45psi.

For the fronts, I didn't have my camber arms in yet, so I planned for the max that I knew would fit, (spacers and hours again) plus 5mm. They talked be down from a wider lip, in order to leave the normal 3-4mm of extra disk space (they do this on all applications to fine tune fit), plus another 5mm to account for the unknown.

Overall, they (well, he, Dave, the owner) did it with a smile and that's the important part!

Look at the bottom of his signature for the HP. It's not a turbo, he's got a supercharger with a limited amount of boost. Yes the ecu is the toughest part to crack.

Best I have from this shoot.

Lips are 3 and 4.5. You could fit a 5" lip out back, but not with Forgeline. The one thing they would NOT do is go with a Rotiform style approach of sacrificing strength for lip. These wheels are track-ready. I think that's important when packing well over 400 crank horse. I can change the whole build and keep these.

Another way to do that would be SSR SP3 style, where the spokes curve back at their extremities. But if I wanted that look, I'd have went with SP3s. Don't care for it.

Perfect in many ways. I love how it sits.

May I ask what tire size you went in the front?

I find bags & boost to be perfect. But I am just a silly little is250 that's boosted
