Just did mine too. I am cutting the side covers this weekend. I will post pics once it is complete.
Yea toms is like 500 buckaroos. Little pricey for me but they look great.
I wanted to let you know that Cusco makes a quick release for these strut tower bars. Instead of always losing up tower screw you can buy the quick release which would be much easier. I am thinking about doing so.
It looks good! Correct me if I'm wrong, since the side plastic covers are off...that means you didn't have to cut into the plastic covers? If so, I really like this setup a lot! I couldn't really see where the strut attached to exactly. Either way, it looks good! Have you noticed any difference in the handling or is it just for looks?

Haven't really had a chance to drive the car hard yet. Yes, I pulled all of the plastic covers off as I thought they looked cheap and blocked al access to see the real engine bay. Just pop out all the plastic screws, 5 minute job to take them all off...
My ISF doesn't have struts, nor does any other other Lexus IS.
I had a STB, Strut Tower Brace, on my G35 and that made a hellofalot of difference. From my research, a Shock Tower Brace in any Lexus IS won't make much difference. See the thread below:
However, if you're serious about wanting to stiffen up the front suspension look no further than the stiffer LCA bushings made and sold by RRRacing or Figs. Very noticeable improvement in all aspects of handling. I luv my RRRacing set.

Keep in mind, if you do read the thread, the G35 DOES have the same double wishbone setup as the IS. Also a coil over shock setup in a double wishbone set-up will experience some lateral load but not us much as a macpherson geometry, so their would be a minimal difference. In the end it all comes down to the chassis design as a whole. If the chassis is already rigid enough you might as well call the strut tower brace a really pretty understeer bar.
^^^^No, the G35 Suspension Setup is described by Nissan as Multilink. A modified McMacPherson strut type suspension that uses Struts not Shock Absorbers. Infiniti specs call out:
SUSPENSION
F: . . . . . . . ind; 1 control arm, 1 lateral link, and 1 trailing link per side; coil springs; anti-roll bar
R: . . . . . . .ind; 1 control arm, 1 lateral link, 1 trailing link, and 1 toe-control link per side; coil springs; anti-roll bar
It is certainly not a Double Wishbone setup like the Lexus IS series.
Below is a quote from the March 2002 issue of Motor Trend.
The G35's 3.5L V-6 center of mass sits aft of the front axles (hence, front midship) and helps the 3369-lb five-passenger sedan achieve a purpose-built 52/48 (front/rear) weight distribution. Added to this founda-tion is an aluminum-intensive MacPherson-strut front suspension with one upper and two lower links combined with a rear multilink setup. But it doesn't end there. Atop all this sophisticated hardware rests an attractive shell whose aero package, including undercarriage diffusers/deflectors and careful attention to airflow over the laser-welded body, nets 0 front lift and a low 0.27 coefficient of drag (0 rear lift and an even lower 0.26 Cd are possible with the addition of an optional rear spoiler). The visage of the G35 should not be taken lightly either. With its stacked headlamps, elegant grille, and high beltline, it signifies Infiniti's intention to portray performance/luxury.
Ok ok, so maybe my comment was to general. Although I see where you might be coming from, It is certainly not a Macpherson strut design, I don't care what some dude in a moto rag says.
Multilink is a little more detailed than I alluded to earlier. The 2003-2006 G35's used a multilink front that has a solid UCA and a 2 peice LCA. This two piece LCA is what makes it multilink, but from a suspension geometry it is standpoint and lateral load it is 1000% more like the IS suspension than a Macpherson strut. Basically the two lower links when connected to the hub act as a the lower wishbone (LCA). The 2007 G35 did end up using a solid lower wishbone/LCA which designated it as a "true" double wishbone suspension. Now.... a macpherson strut design DOES NOT have the upper wishbone style control arm seen in both the G35 and IS because the strut takes on the load vectors that the upper wishbone would take on in a double wishbone design. I have attached a PP presentation I threw together to make my point a little clearer. So in summary, regarding the subject of this thread, I am saying... regarding suspension load vectors the G35 and IS are similar in basic front suspension design versus a Macpherson setup.
This is a good link that explains things, as it points out with a macpherson strut design the upper a-arm/wishbone is removed. The G35 has a upper wishbone arm. http://www.jltechno.com/en/wikibase/...structure.html
