Anyone Have 18X9.5 Or 19X9.5 Wheels With +10-20Mm Or +35-45Mm Offset For Me To Try On My Car?

I need to try bolt on wheels with different offsets to figure out what the hell's going on with my steering. With the wheels directly attached to the hubs, the scrub radius would have been close to zero or negative, now I'm probably too far into the positive.

I've currently got 18x9.5 with +30 offset and that's making the steering pull hard whenever camber presents itself on the road.

I attached 25mm bolt on spacers (so it makes the offset at +5) and that's greatly improved the steering.

So yeah, I'd like to try the wheels and take my car for a short drive to see how it affects the steering behaviour to give me a better idea of what wheels to buy. I'll do all the swapping if the wheels are on your car.

Cheers

Have you had an alignment and shit? The offset should not make your car pull in different direction...

Yes I have and now I'm playing with the settings to make the car behave.

BTW, changing offset completely alters steering behaviour and feel. If you have five minutes to spare, read this http://www.hrsprings.com/technical/scrub_radius

I have what I suspect to be the completely wrong offset for my suspension geometry so I'd like to try some other offsets before buying what could be the wrong choice of wheels.

      Not going to lie. When I just saw this, for a moment I thought it was an interior shot of a VN Commodore...

      Nah, apparently the way to do it is just mess with how much timing the engine uses to try to correct idle. So it massively undershoots, then overshoots, then undershoots, then overshoots. So timing is going from 5deg to 45deg to 5 deg to 45deg. But I kinda prefer the car to not lurch around and have a dependable idle. Given it didn't idle for shit and stalled about 7 times on the way home, still yet to drive it for the 2nd time to see if it's fixed.

      Alright. Many little things have been sorted and the car successfully drove home with an incredibly huge exhaust leak. Unsure if it's simply been awhile, but new heads and cam and intake sound f**kin awesome. It might only be me that notices it though, and it's hard to tell from a 15 minute gauntlet run home and attempting to bleed the radiator. Undertrays on, tools out, road brake pads in, idle un-f***ed, time to do some road tuning. From my commute around town it sounds and drives *really* nice (with a max of like 35% throttle). It'll go to a dyno for a proper before and after once the tune is more roughly dialled in. And @Dose Pipe Sutututu I did learn how to do a proper chop tune at idle. I did indeed even do it, but the car shaking around at idle from the driverr seat made me make it smooth again.. I feared for my engine mounts and clerances to engine bay jank. . After the exhaust is fixed I may mess around with it more. I'm just happy to have it drive around without bucking or stalling which is a WIP.
