Added a new offset/wheel width/tyre size calculator i found - very cool!

i know this has been asked before but what is the offset for 03 sp20 thanks guys

read that..

I'm not real goot with offset tyre sizes etc. and can't really work out the calculator.

But i was thinking of putting 18"x8" Rims on my mrs '95 BA Astina Hatch. Is this possible? or do i have 2 have 18"x7.5"?

What tyre/rim/offset sizes do you guys reccomend?

I reckon u should stick to 18x7.5 if you have strut type shocks. I've got 18x7.5 with 215/35/18 tyres and theres barely any space between the wheel and the strut. Not sure what my offset is but i think its around 40mm.

To make the tyre calc work we really need to know the rim widths too.
Does anyone know standard BA V6 rim widths?
Even better does anyone know the distance from the mounting surface to the standard strut?
Or what other wheels fit? Skyline, etc etc

I4 - 14x5.5, 15x6
V6 - 16x6 (maybe 6.5)

or if you are unsure, go to your garage and have a look yourself

and the measurements you just asked for, dont be lazy, your car is in the garage, get the measuring tape out.

V6 = 16x6.5 IIRC.

:) Not at home ATM I'm interstate, just bored looking for wheels while I wait for a plane. Did I see somewhere that you had an LSD?? If so what did you get/how much etc? (me being lazy again, I could search but ... well ... I'm lazy)

Thanks Rupewrecht

hey guys. i just stumbled across this. thought it might be a little handy ;)

Hello, I'm sorry for being one of those morons who can't figure anything out regarding offset and all that stufff. Is it uncool to just follow the directions on the plate on my car that says what tyres can fit on a 14 inch rim and on a 15 inch rim? Or can you guys help me to get a wider tyre than a 195 60 R15? (Or is it 195/55/r15)

re ask the question, and think about it before typing it first.

Legally you can increase wheel diameter by up to 1" and width by 0.5"
The V6 has factory 16"x6.5" so 17"x7" is about as big as you can legally go without an engineers report. Practically though 205 tires are what will fit between the guards if you don't want to do a lot of number crunching and chasing rims with perfect offsets.
BTW, it doesn't matter if you have an I4 or V6 the chassis is the same.

actually in victoria - it is +15mm/-15mm overall diameter and +25mm max width.

so running 215/35R18 on a 18x7.5 rim would be biggest on a I4 Astina. +42mm to +45mm offset is the way to go.

sorrry but i have no idea how to use those calculator thingos..:(

could someone tell me what the specs would be for a BJ 98 model?

im wanting to get 18's but im worrried about scrubbing of the guards.

what would be the specs for 18's and 17's?

cheers guys

you could probably do 8 inch wide with an offset of about 45.. the tires will be more of an issue though. maybe someone else can help with those

17"x7.5" rim, with 42-45 offset would be best...

If you an 8" wide rim, expect to have to lip the rear guards as they'll scrub ;)

Cheers

sweet, thanks mate.

so 18's are a no no im guessing?

you can, but you might have problems with legalities...

you should be right 18s are sort of legal as you chassis comes with 16s standard for the sp20 am i not correct? or is it 15s.. eithr way 18 is max, well for me anyway, the ba v6 comes with 15s and the bloke at blowjobTmart said going from 15 stock 18 is largest or some thing.. if you do get 18s, 7.5 is a good width ;)
