VEHICLE STORY

Tell us the story behind your ride. What made you pick this particular one? Where did you find it?     Coming from a 2nd gen GS300, that was sold at 300k miles, I wanted another Lexus GS.  I decided to go for what Lexus considered it's top of the line GS.  This particular model is a 2011 GS450h that was bought with 30k miles.  The GS450h has a 3.5L V6 combined with two electric motors matted to a planetary gear ECVT.  This car was most notable for being the first RWD hybrid vehicle in the world.  Further research found that the GS450h is a low volume performance sedan intended for low sales volume.  In other words a very special car.  There were 5055 units of the 3rd gen gs450h sent over to North America.      The GS450h was featured in a Best Motoring International video (2006 #07).  In this video there was a race between a GS450h, GS430 V8, and an Nissan Fuga 450GT V8.  The car beat both of the v8 cars on the track and therefore gave me the impression of a high quality performance sedan.  This was the perfect update for my 2nd gen gs300.       The day of purchase I saw and test drove the car and pretty much just came home with it.  There were 402 2011 gs450h's sent, so seeing another one is very rare.  There is plenty of torque and response for real world driving as well as being extremely quiet.  It isn't a slouch either, the hybrid accelerates to 60 briskly and then switches into it's second speed.  Most other hybrid cars are cvt single stage cars.  The GS450h has a "second" stage when accelerating at high speed, while taking advantage of the constant rev of the v6 motor.         So basically I feel it is a very special car and bet it would last even longer than my gs300.  Of all the mods you’ve made, which do you think offers the biggest bang for the buck?Sway bars have made the biggest difference in handling.  The car corners flat and the ride quality has not been affected.  It allows for a more stable cornering and road manners. No, actually, the front member brace has had a significant impact to how the car feels.  On third thought, a culmination of all the modifications make the car what it is.  How did you go about selecting the specific parts for this build? Any installation tips to share?Research with Clublexus forums and the desire to upgrade the car.  I hope to have one of the best example of this rare car.  The goal for this build is a highly fun daily driver.  Upgrades are thought out to not affect the lexus engineers ideals but rather enhance and do what they couldn't do due to perceived customer desires.  I wanted to enhance the performance sounds so that driving the car is extremely enjoyable.  So far on the right track!  Let's hope I don't stray from this path.What are you planning next?Brace up the rear suspension members.  Look into getting the lower brace for the car, but am worried about fitment of the exhaust.  After this is complete maybe consider coilovers. I have wheels coming soon!What’s been the biggest challenge with this build?Finding parts!  There is little aftermarket support for the 3rd gen GS lineup let alone the hybrid.  Since it is a low volume car not much aftermarket choices are available.  This makes the price of parts on the pricier side.  Name brand tuning parts mainly used.
