[skidjap]

hey all just picked up some new rims for my 32, 16 inch by 8 +10 offset

and was hopein for some help with tyres sizes?

lookin for abit of stretch and open to rolling guards.

32 what?

are u after a aggressive fitment look, or just want something to fit?

my r32 skyline! yea was lookin for the aggresive look defenatly.

car is also quite low on hsd coilovers..

[nisskid]

r32 skyline what? lol

[skidjap]

r32 skyline what? lol

ah sorry hcr gts 93 model and tyre recomendations size wise?

[alr33x]

hi can someone help me (nisskid) seems the expert on this topic i have r33 gtst with coilovers will 18x9 + 20 and 18x10 + 18 fit or what has to be done to fit im guessing a flare? wanting to have as agressive fitment as possible

thanks

[nisskid]

perfect for an aggressive fitment, no flare needed, just roll the guards and stretch the tyres, something around a 215 on the front, and a 225 or 235 on the rear. will be nice and tight, the suspension ur running will come into play however.

[alr33x]

thanks mate! yeh got tein coilovers at the moment.. so spacers and stuff wouldnt be needed?

[nisskid]

nope, assuming they have enough caliper clearance. what rates are the coils?

[alr33x]

um no idea they came on the car, any way of finding out or just take it to a suspension place?

[nisskid]

at the top of this forum is a way to figure out, not a massive issue but if ur going low u want something hard, otherwise ull have scrubbage issues.

Nisskid - what's your opinion on spacers? Dangerous or ok?

Hey NISSKID good to see you running the show here..

i have just put 265/35 on 18 by 9.5 rims on my r32 and their rubbing on the rear guard; do i need to lip guards or will i get away with using different tyres?? i previously had 18 by 9.0 with 245/40 tyres and never had a problem.......!

whats doing??

help appreciated

Nisskid - what's your opinion on spacers? Dangerous or ok?

i've talked about spacers a lot on here, but basically what id say is they are safe if done right. that is decent size, loctite and kept hubcentric.

firstly let's establish the basics, the only thing a spacer does is introduce another mechanical connection, it DOES NOT create any extra strain on the standard hub/studs.

people mainly think spacers cause more strain on the standard hub because it creates more leverage, 2 points about this, 1: putting a spacer in there has no more effect on the standard hub then going a lower offset wheel (for instance putting a 25mm spacer on a +30 offset wheel is the same as going a +5 offset wheel). 2: if anything, ur reducing leverage in most cases as ur bringing the offset closer to 0 neutral (middle of the rim)

a spacer is effectively the same as offset, the only difference is instead of the extra metal on the mounting surface being casted on when the wheel was created, it is being connected there with a mechanical connection.

now that we have that part sorted, there are 3 factors are needed to create a safe connection.

1: the nuts maintain torque on the stud and dont loosen

2: the studs in the spacer have enough metal

3: the studs aren't subjected to much shear force

in some circumstances the wheel nuts just come loose, and since they are behind the wheel, u cant just chuck a wheel brace on and tighten them up, so some loctite is important to make sure they dont loosen. then u have the issue of smaller bolt on spacers, a 15mm spacer will only have 15mm of alloy to hold the stud in, whereas a 25mm spacer will have 25mm of alloy to hold it in, so as counterintuitive as it sounds, the bigger the better (or safer) in a lot of cases. 3rdly when the wheel isnt kept hubcentric the studs are vulnerable to shear movement as the wheel isnt being centre securely and can move around. now the friction between the mounting surfaces stops most of this movement, but i wouldnt trust it alone to stop all of the movement, id rather have a mechanical connection stopping the movement. studs are weak to shear force as they are only designed for torsional force, so they can often fail if they are subject to the shear force.

now all this (besides the 2nd point) is relevant for both bolt on and slip on spacers, slip on spacers however are a lot more vulnerable to shear force, so keeping them hubcentric is much more important.

without offset it's impossible for me to tell u, also GTS or GTR? trying to fit a 265 under stock 32 gts guards is a fair task, ull need rolled guards as a minimum, but u might be able to get away without a flare depending on the offset.

if it's already on the car, ur best bet is to simply look at it and see where it is scrubbing. personally id be dropping the suspension out and lifting the wheel up through the arc manually to see exactly where it's scrubbing, but the lazy way to do it is to find uneven ground, and try and get one side to compress up into the guard, park the car, get out and look where it's touching. either that or jack the car high, then drop one corner onto some bricks or something lol

either that or chuck up some pics and ill try and go off them.

Thanks nisskid. I'll have a chat to my garage about it.

I've got +40 offset wheels on my 33 GTST. They look good but I think there is scope for say +10 spacers to make it a bit 'fatter' w/out rolling the guards.

[livicuru]

Hey nisskid

on a gtr r32; the offset is (+12).........does that help??

Thanks for tips.

[nisskid]

get some pics up if u can, each car can vary a lot depending on alignment/suspension, tyre brand (some tyres protrude more than others, even if their tread width is the same)

[Hank Scorpio]

Skyline model - R34 GT-T

Wheel diameter - 18"

Wheel width - 8.5 [F] 9.5 [R]

Wheel offset - +30 [F] +35 [R]

Tyre size - 225/40R18 [F] 255/35R18 [R]

Suspension - Lowered ~40mm

Modifications to fit - None (Although my camber may have helped)

Sounds like a 245 tyre is what's needed. Or like you said... lip the guards.

At +12 and 9.5in it won't be fouling on the inside, it'll be the guard.
