Tire Width Suggestions

Volcom370Z · 03-02-2011, 01:38 PM

cossie,

Thanks for the pics! why do you say that spacers can hurt performance? seems to be a pretty popular thing on here... the only reason it is even in my mind is because if i decide to put springs on my car or anything like that, i dont want my wheels to looked tucked into my wheel wells

some cars suspesion arent designed to have the wheels spaced out that far, plus a lot of spacers are unsafe because they dont have extended studs.

if you are using the car strictly as a daily driver, get the 265 in the front as it is safer. if you want every bit from your car, get the square setup as it will make the car turn in quicker.

you shouldnt get crazy oversteer with this car unless you have regular tires or screwed up suspension. with the 265/285 setup, car barely got sideways at the track.

The Z, in stock form, has a ton of understeer. I have a feeling it's to help prevent the average driver from killing him or herself out with a relatively high-power, short wheelbase, RWD machine. Still does really well stock provided you don't overdrive it.

yup, thats why they did it. m3 was like that too.

i have seen people run 245 and 305 v12s, i dont know how that car can ever turn!

Local Firestone store sells the set for $1260 before coupons. I got it down to $1160 out the door last year installed and taxed (6%). I like Firestone because they use the machine that has three arms, guarantee to not scratch the wheels. (so i hope anyway). I remember Bridgestone ran a $100 rebate promo on it in April, think it will happen again?

I can tell you that the Z performs beautifully with spacers (appropriate, stud-replacement spacers). I ran 15f/20r H&R spacers at Road America last fall and the handling was excellent. A little extra track width only helps the Z.

Do you think running the 15/20 spacers with a square setup of 285/35/19 Re11s on swifts would be a good combo or would they stick out to far on the nismo? Also, what are you guys doing for camber? This will be going on my DD nismo with the occasional autocross.

m4a1mustang · 03-03-2011, 08:43 AM

Yeah, I never had any issue with my spacers and I definitely felt a difference with the increased track width.

I think ChrisSlicks ran into an issue with one cracking, though.

spearfish25 · 03-03-2011, 09:49 AM

I'd bet money he had a defective spacer.

RCZ · 03-03-2011, 10:21 AM

I ran them for a while no problem, but after hearing some stories, I will never run spacers on the track again.

spearfish25 · 03-03-2011, 11:00 AM

Porsche actually sells spacers as an option on their cars. Horror stories come from poor quality or faulty installation. It's like claiming all tires are bad when you hear a story about a Firestone tire exploding and an SUV rolling over.

m4a1mustang · 03-03-2011, 11:37 AM

The more I think about it the more I agree, and the more I get a hard-on thinking I can put some RE-11s on the 5.0 now.

cossie1600 · 03-03-2011, 11:42 AM

you need long extended studs for spacers, problem is that the best strongest studs are from the factory usually

There is no "best of both worlds" scenario? Companies like Eibach would have to supply high quality materials right? They have a reputation to uphold. Are there a lot of people on this fourm that have had issues?

m4a1mustang · 03-03-2011, 11:47 AM

I've never heard of an extended H&R stud failure before in my life. There is only one case of a spacer failure I have seen and honestly a number of different factors related to or not related to the spacer could have caused it.

Volcom370Z · 03-03-2011, 12:36 PM

After about 30 minutes on Google looking up "wheel hub failures" I seem to only find people in larger vehicles using like 2"+ spacers that seem to have issues, and on top of that it was likely operator error (not tightening and rechecking). H&R even advertises their spacers as adding safety to your vehicle along with better handling... If they knew of possible failure, they'd be pretty stupid to say that.
