Hey Guys,

I am interested in these 19x8.5 Front and 19x9.5 rear for my 3iS FSport.
Would 35 offset front and rear work? I do intend to drop my car on RS-R.



Thank you!

 

It should, however, read this. https://www.clublexus.com/forums/sus...in-s-tech.html

I was surprised that his setup rubbed.

Are you going to lower your car?

 

35 offset in the rear would work with 255 tires or 265 tires if you shave the rear fender

 

Yes, I actually purchased RS-R Coils but then canceled the order because I can save more money on their springs and intending to buy the Super Down Springs.

 

Normally, I would say the 9.5+35 will fit, but in the thread link shown in my previous post, the OP rubbed after getting an alignment.

Atomic350 is running 9.5+38 with 265/30 Conti DWS tires and he isn't having any issues to the best of my knowledge.

I'm anxiously waiting on spotxc to install his super downs this weekend to see if his 19x10+38's rub. If he clears, then your 9.5+35's SHOULD clear since they are less aggressive by 3.5mm. Tire brand plays into it as well, some tires are narrower and have a more rounded profile than others which can make a difference.

 

You really want to be around 40ET in the rear...

 

On springs you shouldn't have any problems if running smaller tires, i suggest going with a 225 on the 8.5 and 235 on the 9.5

 

265/30/19 on 19x10.5et45 on S-techs and it just barely makes it. It would definitely rub if it was et35. But on a 9.5, it should work.

 

jaznraz pretty much explained my situation.

TEIN S.Tech springs
I have 19x8.5 Front with 235/35-19.
I have 19x9.5 Rear with 265/30-19.

I choose 265 because nitto suggest that size is optimal for a 9.5 wide wheel.
I AM rubbing in rear, especially left. I think a 245/30-19 tire would clear, stretchy, but clear. I haven't had a chance to throw one on and test it. If it doesn't, I will probably put H.Techs in the rear and keep the S.Techs up front. It just gives me a headache thinking all the alignments... wheels and headlights.

 

Installation of the super downs coming along......

 

How hard or easy is it to install the springs? I'm not familiar with the IS suspension setup.

 

I can't do it.... I'm mechanically declined lol. I'm at a buddy's house who always does my suspension. Only took him 2-2:30 hours....Not too bad.

 

I personally think that a 10" - 10.5 wheel width (19" wheel) is too much for this car.
You are limited by tire size and over the stock size on the f-sport rear (255/35-18) at best you adding an 1" of rubber - for what, all the grief.

A 265/30-19 WILL fit and be in spec on a 9" wheel in the rear. Any larger in tire or wheel width your asking for rubbing, and a smaller tire will be stretched on the larger width wheel.

Again, a 40-44 offset in the rear on a 9" - 9.5" wheel will fit 'nice'.
You can do a 8.5" up front with a 35 offset or an 8" with a 40 offset.

10"wheel in back stock suspension on 275 and no rubbing at all

 

Jaznraz, I know you've been waiting so here it is. I'm happy to announce I have no rubbing on the setup with the springs installed. Even under hard driving conditions. Looks freaking awesome too
