Are spacers safe?

We've used them for 3 races now without any problems. You should be fine with 10mm. Make sure the spacers are hub centric.

quality spacers are fine.....just be sure to account for them in your budget!!!

I'm not 100% sure.....I could see it go either way...need an official answer?

Thanks for the advice! I bought some spacers.

I dunno, I could make the argument the other way pretty easily if I were a judge. It would go something like this:

We want this race to be as safe as reasonably possible. Broken wheels/tires/brakes are very likely to cause immediate, unavoidable, and unanticipated extreme mayhem and/or unsafe conditions both for the car that is broken and for the cars around it on the track. Because we do not want you skimping on the very parts that most determine your safety (and, more importantly, your safety to others) on the track, pure safety items like wheels, tires, and brakes are free, even though we recognize that there may be a secondary performance benefit from fresh tires, wide wheels, and carbon-carbon brakes.

While an argument that 362-way adjustable Penske remote reservoir shocks (for example) are a safety modification because they aid in better car control thus leading to less mayhem on the track, they are primarily a performance modification with a secondary safety benefit. Similarly, although a 600 HP engine swap straight from Hendrick Motorsports may make you more safe by aiding you to avoid other cars and make your passes more swiftly, it is also primarily a performance modification. Performance modifications are not free.

Which category do wheel spacers fall into: one that if you fail to have them (like working brakes) makes you a danger to everyone else on the track, or one that if you fail to have them it might make you less fast on the track? If it's the latter, then I'd suggest that it's a performance modification and needs to be included in your budget. YMMV. Good luck.

The JAAAGGGG reference was more pointed toward the inboard brakes. Unfortunately I didn't see the shaguar on track when I was piloting the gnome and jeepney last weekend. I was looking forward to it.

Mulry, my point is that if its 100% legal to spend infinity dollars on a set of forged race wheels custom machined to your exact pattern/offset/width/color/smell/taste/shoe size, then a ~$200 set of adapters is a non-issue. As for the safety argument, spacer/adapters come stock on some poortcha 9-11's. Non studded spacers (with appropriately longer studs/bolts) and offset style adapters are used at tracks around the world every day. Sure you can buy cheapo chinese pot metal parts that will be a safety risk. But the same can be said for ANYTHING on these piles of crap that have no business being on the track in the first place.

Of course I'll finish with a disclaimer, I don't make the rules, only read them with the intent of bending or intentionally breaking them from time to time. That being said, I've run offset pattern adapters to put S2000 wheels on my 740 before. Nobody, including the BS judges, said anything. Don't ask, don't tell. Forgiveness > permission. Yadda yadda.

I dunno, I really don't see spacers as necessarily either. In fact, they may be more in the Lemons spirit of "making it work" because the majority of us are getting their wheels as take-offs from another brand/make of car in the pull-n-pay yards instead of calling up Enkei for some 16.5lb Superleggera IIIs with Chro-Moly composite construction and guaranteed "fit" racing wheels. My call is just get a decent pair and don't make a huge ordeal about it. unfortunately, I'd say making a thread probably goes into the "big deal" category
