Impul Rs's

[r33cruiser]

hey guys, all i know is i have 16'' impul rs's with a staggered fitment (normal fronts, deep dish rears).

atm they run 225 tread.

QUESTION 1:is there anyway i can find out the specs on them (dimensions, weight)???

QUESTION 2; also is it possible to run wider rubber on these. a mate is debating with me atm that i can run 305's on there.

so what is the biggest i could go. and how would they do it??

im not 100% but roughly measured fronts at 7.5 and rears at 8-8.5, but not very accurate...hence y i need specs

i love them...light as, but need more rubber soon.

As for dimensions, measure them Weights - do the same thing, get some bathroom scales and sit them on there (minus tyres of course)

305's on an 8.5 rim?

The specs of the wheels should be on the wheels somewhere, either printed in or stuck on by a sticker.

If there's no sticker or any numbers just measure using a ruler, but remember that rim's width aren't measured from inside lip to outside lip. If you measure from one side to another and get 9" wide, chances are they're only 8" wide.

305's could fit, but what's the chances of them working properly.

If they are the IMPUL rims with different width from front to

rear, they can have it stamped in different places.

For the front it should be stamped on the rim facing the outside

of car (you need to remove the trim in the centre of wheel to

see it).

For the rear it can be stamped on the centre of rim,

facing the brake rotor.

The rim diameter, width of rim should be stamped there like

for example "16 JJ 9".

You're welcome.

From what I can understand from the link below (need to scroll down to under the Fig 1,2,3,etc),

JJ means the same size rim as a stock rim (I presume diameter) and JR is the tyre that

fits on that type of rim -

I think some fit 1 over size like 235 on 225 rim with stock R32 GTR rims. But from what I can

remember it makes the side walls of the tyre bulge and not sure how safe it is.

If you want more grip, could fit drag spec Nitto tyres on the rear or fit semi slicks or slicks

but don't drive when the road is wet.
