No, they have the offset perfect so that the wheels sit exactly even with the fender and no rubbing on the inside. There is lots of room on the inside of the wheels as well. They manufacture these wheels in their shop to fit any car you want. Apparantly they have done lots of Ferrari's because the wheels fit perfectly. | ||

Wow! Those wheels look great - car looks great too. Do the 10" rear wheels and tires extend beyond the body of the car? Any clearance problems at the back of the car? | ||

John I recently had new rims built by "http://www.usacomp.com/"in Pennsylvania. They did the off-sets to fit the 308 body 8" fronts and 10" rears. I'm running Michelin pilot sport 255zr/40/17 on the rear and 225zr/45/17 on the front  | ||

Other than those two items the transmission itself is definitely gonna have more stress on it with all that extra grip. I was thinking about this while driving this afternoon. I like the 360 rims and think I would like the 355 rims too, but I'm tempted to look around for aftermarket rims instead and get something made to fit. Roughly 18x7.5 and 18x8.5, then run 225s and 245s. I should have quite a bit of time to think about this stuff before I'm ready to switch. Paul what tires sizes are you running? David what HREs are you getting? How much do most aftermarket rims (HRE, Speedline, SAC, etc; real nice rims not just average ones) cost for a 308? | ||

I've also read, don't ask me where, that the rear axles are questionable with increased traction due to racing rubber and maybe significatly oversized tires. I took steps to upgrade the fatigue properties of the axles during a recent rebuild. | ||

One thing that you should think about is the ability for the rear wheel bearing assembly to handle the increased stress from the grip a tire on a 10" rim would cause. I have been told that the greatest weakness in the 308 is the outer rear wheel bearing housing assembly. I would not recommend anything over a 245 size tire on a stock (bearing housing) 308. | ||

Thanks Steve. You maybe right. I�m going to take the rear wheels off and make some measurements. Will let you know what I find. John | ||

JPM -- yes, both the front and rear 308 nominal wheel offsets are ~+11mm (i.e., the mounting plane of the wheel is shifted 11mm towards the outboard side of the wheel from the wheel centerline). Most of the later model wheels have much larger + offsets (like +40~+60 mm) so spacer/adapters would be required -- but I too am doubtful that you'll be able to run 10" wide wheels on the rear of your 308QV (without having the outboard sidewall of the tire sticking way out past the coachwork). | ||

Paul, you better get ready for Sunday. Are we going to have printed menu's? Thanks Bret, the car has been under the knife for a while. Had an engine rebuild, next week its going to Paul for the new ignition system. Can't wait to get it on the track next month  | ||

I�m going to do some measuring of my own to see if the 10� wheels will fit in the back. Stock wheels have +11 mm offset with the offset towards the front of the wheel. Is this correct? I�ll let you know what I find out. Thanks John | ||

David, Before you drive over here you should wait to be invited as this is a pretty exclusive area :-) Tracking with spacers is fine as long as they are made properly (360's have spacers as an option). Paul | ||

I forgot, don't be worried at all about spacers. They work just as well as not having them for all intensive purposes. Porsche uses them stock from the factory all the time, and we know how they are admired for their durability, etc. | ||

Paul's 4 fronts are 18x7.5. I know that a 8" wide rim will fit in front, but I'm not sure about the 10" in back. If it will fit that would be a hell of a lot easier because you can simply buy a set of 355 or 360 rims (550 will be too wide I think, 10.5 in back, starting to push it). I'm very hesitant of a 10" in back though, I would check with the dealership around you first before doing something like this. If they say it will fit then go for it. Somewhere in the relatively near future I will be switching to either 355 or 360 rims (apparently the 355 are a lot less, but there are a few benefits of the 360s, other than less weight they are also aluminum and therefore more durable). To get the rims I'll most likely go through my dealership, so I'm gonna pick their brains about sizes when the time comes. | ||

Thanks for the input guys. Not planning on tracking the car but I also am concerned about using spacers. Seems to be the only way to get larger factory wheels to fit. As for tire sizes, I was looking into 225/45-17F; 255/40R or 225/40-18F; 265/35R. Due to $$$ involved, I really want to make sure the 8� fronts and 10� rears fit before committing. John | ||

I currently have speedlines, just ordered HRE's though http://www.focfloridaregion.com/images/MVC-002F.jpg Might drive the car over to Paul's home and take some photos of both cars. | ||

You know, I was just thinking about Pauls car. It is an outstanding specimen! I have seen a 308 QV with huge BBSs on it and the car looked incredible. I have seen 308s with Mondial wheels on it, and a 308 with 355 wheels on it. All looked really nice. | ||

I think you'll be fine using either both 17 or 18. I would not recommend spacers if your thinking of tracking your car. What size tires are you thinking of running? | ||

I agree! Actually, Paul's car was an inspiration to consider this type of look. I contacted Paul and he said he used 4 front wheels. I was wondering about the problems caused by using 8/8 1/2� fronts and 10/10 �� rear wheels. | ||

I am looking into wheel options for my 308 QV. Want to go to 17 or 18 inch wheels for a more modern look. Does anyone have any info regarding fitting factory 355, 360 or 550 wheels to a 308? Really like the simple looks of one piece wheels rather the modular look of HRE or Speedlines. I understand that it probably involves spacers to adapt the wheels to the factory hubs. My question is about the maximum wheel width that I can fit to the car. HRE lists 18x8 fronts and 18x10 at the rear as an option for the 308. These are the roughly the size of the 355 and 360 wheels. Will these fit without modification of the fender liners? Will there be any interference at the front suspension? I would keep the overall wheel/tire height close to stock. Any input would be greatly appreciated. John |
