The R888's run wide. I wouldn't put a 295 on a 9.5". My guess is once they were pinched on a 9.5" the 265's would be pretty much just as wide.

 

Glex - any chance you have or can take some pics of the setup and the modded bracket? Are you using the APS oil pan? I have small straight fittings that convert the 1/2 BSP to -10AN fittings right out of the plate and then 90* fittings off of those. Are you using 90* or 45* fittings off the plate?

I have the oil temp in the old APS turbo drain plug and oil pressure where the stock pressure reading unit used to be. I suppose I could eliminate the coolant plate all together as the car isn't ever going to see real cold temps

Here is the area I'm working with:



I know the tires aren't recommended for 9.5" rims, that is why I was asking if anyone has mounted them before. I'm running 275mm right now and I'd hate to get thinner to a 265mm.

 

Pics of the mods to the crash bar and setting up the coolers:



Frank mounted the coolers flush to the bottom of the crash bar and we ran the hoses through the top section of the hollow bar. The writing on the bar is from me when I reassembled the car this last time. We had to relocate the PS cooler and it fit tucked in right here:

 

Pics of the setup on the bar and how it looks with the front on. We got pressed for time so I forgot a full frontal shot. I will get it and post it up tomorrow if I can.

 

I thought you did this to count for every failed engines you had

 

Sorry Cass for the late response but no I don't have pictures
But Randy's setup was the same one Jeffie did here



You see the elbow fittings I put them where you see the factory oil cooler line is routed towards that little cut out on the APS pan facing towards the front of the car ( Picture #2 that you posted) and just cut the bracket to have enough clearance. It was tight but it fit

 

hahahahah i see my car on the lift in the background..

speaking bout oil coolers.. ima have Frank upgrade my lines on mine cooler.

 

Im running 295 wide KDW2s on my 9.5" Volks with no problem, i was worried i would have issues mounting them since its "not recommended" but the installer said it was a breeze. Although im sure i could get more traction with the same tires mounted on a 10.5" wheel you gotta work with what ya got.

And i wouldn't recommend running a 30 aspect ratio, not enough sidewall and will hurt traction, im running a 295/35/19

 

Sidewall of 35 is that much better than 30 for traction? LOL.

The important thing to realize is that it represents a proportion of the width so a 305/30 is roughly the same sidewall as a 285/35 and you want to maintain similar overall wheel height ratios front to back so as not to upset traction control (and speedometer reading) too much.

 

I didn't say it would be significantly better, but without a doubt a taller sidewall helps.

Have you ever seen traction control problems caused by tire size? I have seen alot of crazy staggers and yet to see anyone with ABS/VDC issues cause by them. I run 295/255 both 35 ratio, i don't like the way a 295/35 looks, its almost square (in my case would be smaller OD than the front) and a taller tire has the same advantages a 3.3FD swap does.

 

I think that traction control problem is a bunch of hooey. I'm running stock height tires in the front and 2" larger diameter in the rear with not a single abs or traction control issue. 2 years and running this way so far without any issues. It's well over the "4%" they said would cause the traction control to disable and throw a code.

I didn't heade the warnings and came out just fine with tires that now only break loose in 2nd gear

 

^^ I've had VDC/TCS issues just from having new rears and worn fronts -- stock rims and tire sizes 245/45/18 and 225/45/18. The thing would kick in just coasting down hills and slow corners...So yea it happens, I guess some version ECU's care more than others.

 

I had that same issue, and it was a bad wheel bearing, nothing todo with tires.

 

+1 djamps. I've had the issue with mismatched height and with mixing old vs worn back to front. Not a wheel bearing issue. Different model years may behave differently.

 

I guess you would know better, since i spent all that time replacing the ABS unit, G(yaw) sensor, wheel bearing sensors etc and as soon as i replaced my right front wheel bearing it went away and have not had an issue since.

Me and Djamps both have 04.5 Gs for the record.

But anyway back on topic, Cass do it, its not ideal to run a 295 on a 9.5" but it is a traction improvement over a 285/9.5" i know first hand.

 

Sorry no offense - meant it's not only caused by a wheel bearing issue. Also have a 04.5 G. Different trims of the Z definitely have different behavior in addition to different model years.

 

Thanks guys, I'm just trying to put as much contact down with as sticky a tire as possible. I've even looked at the Hoosier racing slicks, but am concerned about getting caught in the rain on the way to ZdayZ.

As far as VDC/TCS and such, the lights come on, but the ViPEC is in control of the drive by wire system so nothing happens.

The car is going back to the alignment shop today to have it redone, it pulls left when the wheel is pointed straight . I read up some on camber settings for the rear and hope I can somewhat correct what looks like significant inside wear vs outside. Too much camber I suppose?

As far as hooking up the coolers goes, I suppose we will remove the APS pan and try and get the Mocal plate installed and then see if we can put the stock plate on as well. If not, I will either eliminate it or possibly switch to the stock pan with an AAM spacer. I am no longer using the APS turbo oil returns on the pan anyhow so I don't think the pan is a must

I will research a remote oil filter setup today as well, that may be the easiest solution, but space is tight down there.

 

I'm only running 275mm out back right now. It looks like I may need to roll the fenders in order to fit anything wider. Are yours rolled? I'm pretty low as well.

Here is a link to me having some back road fun with the 370Z guys. The road was crap and I bottomed out hard twice. I didn't see the sign cautioning lower vehicles and custom exhausts

Yes mine are rolled, alot of that depends on your offset. I had to roll mine when i went to 285s and luckily it was enough to hold 295s (not sure my offset) but its so close that if i put a thick layer of tire shine (gel) on it rubs off

 

Damn Chris those were some nasty roads... group deal on rim repair and alignment afterwards?
