G35Driver - Infiniti G35 & G37 Forum Discussion

I'm thinking we can possibly sticky this... I searched around but didn't find a definitive thread

Let's compare:
FRONT STRUT BAR
List:
a) design
b) clearance issues
c) ease of installation
d) type of metal used,
e) price
f) links for more info
g) which fit coilovers

ARC Bar
a) Three piece bar - engages three strut bolts on either side. Arch across the top of the plenum.
b) May interfere with coilover adjustment knob positioning - one of the bracket support bars crosses right where the hand adjustment knob should be. EDFC shouldn't be a problem.
c)
d) Titanium...
e) $1040 retail. $936 @ http://www.injectedperformance.com/e...t.aspx?ID=3820
f)
g) does it fit coilovers? need input!

Circuit Sports bar
a) One piece bar
b)It does rub the OEM engine cover and it even rubs the OEM engine hood insulation panel, but it does not cause any hood closing issues. Also due to its solid construction, no access holes are provided to allow access to hand-adjustable dampening suspensions.
c) installation is easy, move some brackets and tubes out of the way and it slides into place, bolt down with OEM strut bolts.
d) reinforced aluminum
e) $135 from Phase2 motorsports
f) http://www.phase2motortrend.com/strutbarbraces.html
g) does it fit coilovers? need input!

GT-Spec Bar
a) Three piece bar - engages three strut bolts on either side - one of the arms on the bracket has been moved to allow installs with most adjustable coilover systems.
b) It will clear the Motordyne 1/2" spacer (CERBERUSlucid posted pictures) also clears 5/16 spacer as expected (thelarsky)
c) user

Installing the mount on passenger side is very easy (~10-15 minutes with a breaker bar). Installing on the driver's side does require moving A/C lines which are in the way, but only until you get it seated. Everything you move can go back where it belongs once the bracket is installed. I think it took me about an hour, but only because I'd never done it and didn't know what to move where.
I have zero fitment problems with 5/16 spacer & no engine cover.

to confirm, I have 1/2" spacer, Ztube and engine cover. GT Spec is adjustable and fits without rubbing the hood lining.

Richie's V1 bar (ARC Replica)
a) Three piece bar - engages three strut bolts on either side
b) May interfere with coilover adjustment knob positioning - one of the bracket support bars crosses right where the hand adjustment knob should be. EDFC shouldn't be a problem.
c)
d)
e)
f)
g) I attempted it with JIC FLT A-2 coils and it was a FAILURE - will not fit with the knobs. I assume this would be the same for ARC since Richie V1 is a direct copy.

Richie's V2 Bar
a) Three piece bar - engages three strut bolts on either side - one of the arms on the bracket has been moved to allow installs with most adjustable coilover systems.
b) V2 was made to allow hand-adjustable coilover knobs
c)
d)
e)
f)
g) the modification was made to allow coilover knob adjustability.

Relentless Auto Bar (same design as VRT)
a) three piece construction
- engages two of the strut bolts and the anterior A-Arm bolt
- must be installed with front of car in the air - active resistance once lowered
b) no plenum spacer issues, G/Ztube and Stillen Air intake and Stock box must be shifted towards the center of the car about an inch to fit.
c) probably the most difficult to install
d) "chromoly steel"
e) retail?
f)
g) from my VRT experience: it should clear coilover systems with the knob sticking out the top. I have VRT installed with Tein mono flex & EDFC. The bar avoids that area completely. RA should be the same since it is the same deisgn

Stillen Bar
a) Three piece bar - engages three strut bolts on either side
b) Will NOT fit 1/2" spacer (Confirmed by SteveZ) and <<will NOT clear OEM intake (Confirmation?)>>! it WILL fit 5/16" spacer
c)
d) 6061-T6 Billet aluminum
e) Retail $239.15

g) does it fit coilovers? need input!

VRT bar (discontinued- a few in circulation - some are made to clear Stillen S/C) - the original design was made to fit JWT TT kit!
a) three piece construction
- engages two of the strut bolts and the anterior A-Arm bolt
- must be installed with front of car in the air - active resistance once lowered
b) no plenum spacer issues, G/Ztube and Stillen Air intake and Stock box must be shifted towards the center of the car about an inch to fit.
c) probably the most difficult to install
d) chromoly steel

RareJDM rear brace
Rare JDM Rear Strut Tower Bar
a) ~1.5" dia. chrome moly tube mounted between two welded steel brackets. Bar is attached to brackets with threaded hardware, allowing user to adjust pre-load on the bar. The threaded hardware also allows the bracket to pivot slightly. Brackets are secured to the car through existing holes in the trunk. Bar sits slightly forward of where the Stillen bar sits and is centered between the shock towers.
b) See pix in this post. In a coupe, it sits 1-1.5" above the false floor, leaving the area above pretty open. You can still slide items through the backseat if you need to. The threaded attachments make it easy to remove the bar quickly if you need to - takes about 5 minutes.
c) Installation takes about 30 minutes, with the majority of the time spent cutting slots in the trunk liner so the brackets can poke through. Install time will be a lot shorter if you don't care about concealing the brackets or making clean slots for the brackets.
d) Chrome moly tubing & steel brackets
e) Initial run was at $350 shipped
f) https://g35driver.com/forums/picture...ar-teaser.html

"What to look for in a strut tower brace?
When looking at a strut tower brace to give you the most benefit, it should have the following features:

-Sufficient protection of the strut tower top (to prevent "mushrooming")
-No pivots or heim-style joints to allow the bar to flex or bend, but adjustable, to allow for intention suspension changes.

http://www.rebmw.com/Merchant2/graph...stb/hinges.jpg

-Center bar with minimal bends or kinks (straighter is stiffer!)
-Provide adequate underhood clearance (so not to dimple the hood)
-Allow for suspension changes (for those that frequent the track)
-Made from the best materials available (for lightweight, coefficient of thermal expansion)
-Even BMW applied many of these traits to their own strut tower braces when they offered them. For the E36 and E46 models, both used cast aluminum strut tower plates and matched them to tubular steel center bars. "

I'll clean up this thread as people respond and add info. I hope this thread will help keep g35driver more simple - ex: the shocks/coilover thread is MONEY! This will just complement that thread. :-D
