I am thinking of putting the Tanabe Sustec Front Strut Tower Bar on my IS250. I currently have RSR Down springs and Hankook Evo 2 Summer tires. I go through the canyons quite often as I live on Angeles Crest. Is it worth the $140.00 price tag? For those who have it on their car; how significant was the difference? Also, any difference on comfort while regularly driving?

I have the cusco strut tower bar and honestly I can't tell the difference. Maybe if you drive the car hard but everyday driving, nothing. It does look bling though

If you want better handling performance, I'd give this a try. https://www.clublexus.com/forums/cl-...stem-usrs.html

I'll definitely take that into consideration! Thanks for your help

Instead of the Tanabe front tower bar, the Tanabe front under brace is what you'd want to get to improve responsiveness from the chassis: http://www.tanabe-usa.com/rnd/post/T...n-F-Sport.aspx

Ride comfort will remain the same.

You will definitely feel the difference in handling and front end stiffness when using a combination of strut tower bar and under brace. The front end feels more solid, a crisper turn in and no loss in comfort. I've driven my IS with this setup for some time, but had to uninstall these parts because the hood of my car is not perfectly aligned after repairs (the car has been heavily damaged) and interfered with the tower bar. I've bought the Cusco bar instead - it's thinner than Tanabe one and should not touch the hood insulator. A friend of mine runs a healthy 3IS with Tanabe Tower bar & under brace - the fit is ok and the same positive driving experience )

the unders brace is only available for RWD models. I leanred the hard way.

The OP did not specify if he runs RWD or AWD car. RWD is a default option )

Is there a tower brace for a 2015 AWD IS350 yet?

Imprezario

AWD and RWD use the same tower bar.

My car is RWD fellas. Thank you so much for all your input. I've decided to go all out and do the tower brace and under brace and a IS-F rear sway bar which I picked up for next to nothing . I appreciate all your help!

Swacer

Are you positive? I remember hearing that the mounting locations for the AWD were different?

Also, I went here:

http://www.tanabe-usa.com/towerbar.asp

And was not able to find a listing for IS350.

is it somewhere else? Does the vendor come on this forum?

Imprezario

Wow, Tanabe removed the whole 3IS lineup from the tower bar catalogue

Swacer

The vendor emailed me back, they said they do not offer ANYTHING for the AWD IS.

I am very disappointed in these aftermarket companies, its a very bias to the RWD model

Did you need to modify your engine cover?

Imprezario

The right edge of the cover slightly touches the underside of the tower bar only when the engine is warmed. Don't think it's enough to cut the cover.
