I'm waiting for the following to arrive - Hard Race front sway bar, Toms GSF mid cross member brace (fits the 350) and Ultra Racing rear lateral braces! Lets count the forged light wheels too because they made a difference as well.









Yes after awhile I found many items listed of UR on ebay. That's really a nice collection of chassis braces you have there. I'm sure it corners pretty flat at any manageable speed.

Also yes the reducuction of rotational mass weight is a big plus. I think I will start there first over any suspension mods at the moment. As to what fits correctly I need to search around. I'm really leaning towards some Enkei GTC02's at the moment. Since I have the PF01's on another car now. Though usually on Enkei's they have a 1 inch step up on the barrel. I'm thinking the F Sport calipers might be too close. Therefore it might not be able to clear the wheel weights, and knock them off. It's hard to get Discount Tire to move the weights to the center of the barrel to clear. The SA will listen when purchasing tires, but to get the ST mounting them. Is a whole different story.

Try these. I installed them on my GS, they really work well along with a few other Suspension upgrades I have too. Tightening up the sloppiness from your Rack is always a great place to start. Put my GS on Rails, big difference right away in the sharpness and feel.

Yes sir thanks for the heads up. I love razor sharp steering input. Though I would like if they weren't collars. On the 2IS this is what I found out while removing my AWD 250's rack bushings. They were a 2 piece design like traditional rack bushing. Not so much on the RWD it seems it was a PIA to remove, but doable.

As for the chassis braces I also experimented with my own made inhouse braces. The one 4 point on GS near the resonators is it a flat surface? The OEM looks like it's raised in the front. I think some shields for the rear differential were put in place to silence the differential whine. I could be mistaken though as I have to search for that thread.

I have had the Invidia q300 and the apexi exhaust is currently on my car with the aimgain diffuser. I like how the apexi sounds when I start it up it has a nice sound especially when it’s a cold start. The Invidia was like a mild upgrade from the stock and came to life when you get on it but was better for daily driving. The apexi is much louder and when you cruise you can here it even under 2000 rpm

My Friend has the Apexi. Its was very expensive, let alone you got to then buy a expensive diffuser too. Its Loud, when you have 2 tips exiting each side a exhaust that loud does get louder. Other friend has the Borla, it was not as loud as the Apexi, until he put Headers on, then it was way loud too. The Borla sounds like a Mustang, want to sound just like a Mustang, get a Borla. lol!

I have the Tanabe with Headers and other. Sounds just right with the Mods I have. One thing I do really like about my friends Apexi, is that it is the deepest sounding GS350 exhaust sound I have heard. I mean you can tell the difference deep and low. Still too loud for me, but I do like how low and deep it is.

I love the way my Invidia Q300 sounds. Very nice and quiet idle until you hit the throttle.

I used to have a 3 series ZHP variant. It had a perfect exhaust, in my opinion. Just a very light rumble. The Borla video, for me it's too loud.
I wonder which one would be similar to one I am describing?

If anyone wants to hear more of the Borla. I got some clips in my video here. The Borla sounds amazing, no rasp at all!
