biggest spacers without changing studs

Footloose301 · 07-31-2012, 06:12 PM

I'm running 15mm in the front and 20mm in the rear and I launch hard and Auto-X the car and never had issues. I have the replaceable studs. H&R DRS Spacers.

Lots of people like the built in studs (call them V2 for purposes of this thread) and have never had an issue however I chose the extended studs for the following reasons...

Less mounting points hence less chance for error... with bolt on spacers you have two sets of surfaces needing to be bolted down
Increasing number of studs from 6 to 12 per wheel... again more areas to potentially fail
Inner lugs hidden and harder to check torque... potential to come loose without you seeing

Not the end of the world to get the bolt ons but I'd rather spend more time at install knowing I am secure... it didn't take long at all to replace all the studs and the price difference was negligible in either direction.

I'm calling Nissan. They ripped me off. I have 5 studs per wheel!

Wheee! a forum member did a great write-up in the DIY section on how to do the H&R spacers and how to switch out the studs too which is very easy to do.

If you don't possess a garage, the DIY ability or the tools a shop with a lift should take between 1 to 2 hours to do the whole car for you. Wheee! and I did my spacers and new intakes in 3 1/2 hours in his garage.

Personally I wouldn't try any size spacer without longer studs.

if it's a hub-centric wheel like our Z's you should not use spacers that do not have the centering lip. even if it's 5mm there's a taper on the center bore (wheel side) so the wheel will not sit correctly.

if it's aftermarket wheels using tapered lugs you can go 5mm usually; you want 10mm thread and use steel lugs in this case. do at your own risk.

H&R 20mm front, 25mm back bolt-on spacers. No wobble, easy setup. As another person said, bolt them on, run them for approx 50 miles, then take the wheels back off and re-torque.

You don't have to replace the studs if you don't want to. Literally hundreds of cars have used this setup without an issue.

Even the Porsche GT3 runs spacers in the rear. Don't worry about it.
