We use both types of spacers. There isn't an inherent problem with either design provided that they are built correctly and torqued properly to the hub and the wheel. Obviously if your bolts are loose, you're going to have problems with or without spacers.

As a typical rule of thumb you use bolt through up to 20mm and bolt-on for more than 20mm.

Also remember that anytime you've retorqued the wheel bolts and especially when using wheel spacers that you need to re-torque all bolts again within 50 miles. With wheel spacers I do recommend that you retorque everything several times in the beginning to be sure that all the surfaces are flush, all parts are mounted correctly and that the bolts are retorqued and everything has settled.

Wheel off to check torque?

Thank you as always for your explanation. Dumb question no doubt, but I assume then that to retorque the bolt on spacer, you have to take the wheels off to access the spacer bolts? If so, maybe it is easier to not be too aggressive in the spacer width. That way one can use the bolt through rather than the bolt on so you only have to retorque the actual wheel bolts which are exposed, i.e. no hidden bolts to be concerned about.

Are the QP spacers bolt through or again is it a function of the spacer width? If bolt through, how easy is it to swap out the stock bolts? Another dumb question, but are the stock bolts screwed in or pressed in from back side of hub? If pressed in, that doesn't sound like a DIY job, at least for me!

QP Sport,

Retorquing the bolts is not a big problem. You'll torque everything 1st time and drive the car. Then take the wheel off, recheck / retorque the spacer bolts, put on the wheel, torque the wheel bolts, drive the car and provide one last check / retorque to be safe. This is the safest way to get the job done and know that everything is torqued safely.

The design is a function of the width of the spacers ( at least the way we build them ).

Installation is fairly easy, the pieces just bolt together with either design. The spacers are all hub centric and fit together like legos with a perfect fit.

All the bolts screw in to threads from the front, just the same as stock. Nothing is "pressed" in and nothing comes in from the back side.

Installing these takes 5-10 minutes a wheel, very easy.

Best Regards,
-- Jeff

Boy that was sure a dumb question I asked!

Thanks Jeff,

I don't know what I was thinking when I asked about the bolts. For some reason I was thinking the wheels were attached to the hub by placing over bolts which were part of hub, and then screwing on a nut. Forgot that when I changed tires there was no bolt protruding from hub but that you attach wheel by screwing bolt through the wheel!

Jeff,

When can we expect the QP Spacers to be availble?

Thanks
We have +15mm sets available now. Contact me directly for details, the website should be updated soon as well.

I just put on some spacers in the rear today from Formula dynamics on my QP, had them custom turned at 10mm, and they look great. So far, feels great, rides great, looks great. No problem. The quality of the spacers that Jeff is using is definitely definitely more than high enough quality to be OEM or better. So if you guys are looking to try some spacers to complete the look, definitely go with FD products, I noticed with the wider spacers that the car handled a little flatter, which is a great improvement over an already excellent suspension setup on the QP sport gts.Thanks JEFF! And thanks to the guys at UNIVERSAL AUTOSPORT!! (KENT, ANTHONY) Thanks guys!

When you get a chance post some pics. I'm looking to add them myself but Jeff has 15mm & 22mm kits. So I need to decide which one.

MaseratiSportGTS has a set of aftermarket wheels so we built him a custom size.

Typical install sizes would be +15mm to +22mm rear. The fronts can use a bit also, we're thinking about producing a smaller size for that. However it depends on your year and wheel configuration. Hopefully, I'll have pics up soon.

Best Regards,

A Must Have Mod!

We (Universal Autosports) have installed a number of FD wheel spacers with no ill effects. Yes, there is more load on the bearings, but not much, far less than sport springs or driving to the traction limit. Anytime the rim offset (how far in or out the wheel sits in regard to its mounting point) is changed, the loads will change as well. Maserati runs the same bearing with deep dish rims and slicks on the Trofeo race cars with NO bearing issues. Jeffs' products are top shelf, I would not install them if they were not, and the driving result is improved handling via a wider track. Cosmetically they REALLY look great, on a GT or QP and fill out the wheel well properly. I put the spacers on the must have list with the DBW and sport springs!! --Kent

Thank you for your input as always! I would be interested in knowing what spacer width you would suggest for a 07 QP Sport GT. Would you do both front and rear or just rear?

I realize the answer is in part subjective, i.e. what look one wants, and what performance characteristics one is attempting to achieve. However, if you were able to suggest a single best "all purpose" set up, even if it is a compromise between the two, we QP owner's would be most thankful!

Wheel Spacers will not add to tire wear. They just spacer the tire out wider the same as a performance model wheel (OEM or aftermarket) would do.

Those EBay wheel spacers sure look scary. These are the chinese made product that are attempting to fit every make and model of vehicle. They are cheap because they can produce lots of them but the spacers pictured will definitely not work on any Maserati.

They are not hub centric (will cause vibration)
They use studs not lug bolts (not compatible)
They are 12mm instead of 14mm (not compatible)
They are 31mm which is too large for any current model (unless you like the civic look with wheels protruding out the wheel wells!)
They are much weaker as they have quite a few holes drilled to fit different vehicles.

This is a classic example of where the seller looked up every car they could find with the same bolt pattern but ignored everything else that matters. Unfortunately there really isn't anything compatible with the Maseratis. This is why we've custom built spacers for the vehicle.

I'll have the new pictures and specs up shortly on the website.

Best Regards,
-- Jeff
