The stock studs hold the adapter to the hub, the studs you see are the ones in the spacer.

sorry, correct

also, I am not keeping the 60 series tire!

I want to know why a 245/45/16 would be a good or bad choice for auto-x compared to 225/50/16 - other then availability and price and ability to rotate

too much tire? meaning?

On my car, I run 205/55 and 225/50 on 16x7 front and 16x8 rear, respectively. It works fine for auto-x. If looks are important, I do think that 225/50 front and 245/45 rear would give a better look, but wouldn't really mean much for an NA in auto-x. Much more important to play with tire pressures, etc. to dial in handling you are looking for. Tire Rack has good information on overall diameters for various sizes and brands. If you change to non-standard diameters, you will introduce speedo and odometer error, which may or may not make a difference to you.

stock for those cup 1's on a 968 are 205 front, 225 rear

yes, but the car doesnt see much street time, as funny as it sounds, only driven 15mnts/day for around 15miles, so its safe, and out on Sunday cruises with a "wild bunch"

I thought that 245/45 would mean wider tire same height = so the car is more leveled and has more patch in the rear, thus more grip

I also want to note, that car came stock with small roll bars, but its OK to upgrade to the bigger ones, should it not apply the same way to tires? I mean, these are not stock wheels to begin with (on this model/year)

I am still wanting answer on safety, local guys say it should be allright and that it should be safe, and not much wear/tear introduced on other parts

Re safety: I'd say you are ok considering how the wheels won't be "hanging *** out" with af unky effective offset (ie tire section is relatively inwards with regards to those wheels)

ah then they are adapters not spacers ... phew .. anyway good luck with the project..

theykallmekem

yeaa, plus one with iceman, that confused me >_> 225 are fine imo.

when i convert to 16in, my plan is to go 205/50-16 in front and 225/55-16 in the rears. sounds close to your specs, but take measurements in case they rub, hoping mine wont rub TOO BAD

its a spacer

did a search on google by the # on the spacer, here's what came up:

any suggestions on the tires?

I was thinking Hankook RS2, looks like everyone loves them

Bud that's an adapter. It's called a spacer, but it's really an adapter.

An adapter is so because it bolts onto your stock studs, then your wheels bolt onto the adapters.

A spacer is just that, a spacer. It's usually an aluminum piece that slides onto your stock studs to go in between the wheel and the hub.

Quick question......did you buy the car this way? what was it's purpose before hand.

Quite possibly if it was an autocross car, the previous owner could have used the 8"s in front as a cheap way to get rid of the 944's natural push and actually allow the rear to come around easier having less grip in the rear, considering the stock tire sizes matches the corresponding wheel widths.

Possibly the autocross courses he participated in were very tight courses with little high speed turns, so maybe that's the reasoning for the reversed widths.......if this doesn't apply to you, disregard.

By all means for daily driving, the 8's need to go in the rear. Right now, I've got 16" D90's and I'm running 205/55's in the front and 245/45 in the rear. The down side of this is the car tends to push a lot more than factory, but the 245's look a little better and they last a little longer than the 225's.

Relaxed:

when I bought the car I didn't get any paperwork/maintenance records with it

I have no idea what the car was used for or where/how it spent its life before I got it

from what P/O told me, it was a friend's car, and she only drove it on Sundays

spacer/adapter, for what? its an adapter that works like a spacer ... what am I missing here? yes the car came like this

when I got the car, all tires were same size;

rear tires wear out: wheel size is 16x8, I have a set of used tires put on these wheels, and decide to move front wheels (which were 16x7) to go back because they had like new tires

I didn't know wheel size when I did this though

so now that I know, 8's are going in the back, and 7's are going in the front

the only thing I need to figure out is, what's the deal with the spacer, what tire size would be ideal - if I want to autocross the car - and what tire would work good (if TireRack still had that deal on RE's I, I should have picked them up! such a great price)

it's all in the semantics roman, a spacer is a plate with holes in it , it willslap on to your existing hub put give you less stud to work with . An adapter is a spacer with studs welded to it basically . you put the thing on and still gives you proper stud length. Yes they may all be generically called spacers by lazy *** vendors but we try to be correct here
