Questions
Q: What is a proper way to break in a new car or a car with
a brand new engine?
A: Generally you want to break in the car for the first 1000
miles. Try not to over rev the engine much above 4k rpm and
try to not to keep a constant speed for very long and do not
use cruise control.
Q:
When should I get my first Oil Change?
A: There is much debate on when you need you first oil change,
Toyota says 7500 miles, some say right after break in at 1000
miles. But a good general rule of thumb is around 3000 to
3500 miles.
Q:
What kind of gas should I use for my GT/GTS?
A: For the GT the owner's manual recommends 87 octane regular
unleaded fuel. The Celica GT is not designed to take advantage
of higher octane gas, so while putting it in will not harm
your vehicle, you will receive no benefit and the cost is
significantly higher. If you are hearing a "knock"
or "rattle" sound from your engine during high load,
and the problem is reduced or eliminated by higher octane
gas, then you probably need an engine tune-up.
For the GTS the owner's manual recommends 93 octane gas due
to the higher compression ratio/higher performance engine
in the GTS.
Q:
Will aftermarket parts void my warranty??
A: The only time a mod will void your warranty is it is proved
that that aftermarket part is the cause of failure of a part
covered under your vehicle warranty. TRD parts, if installed
by a toyota dealership, will not void your warranty, infact,
they will be included in the remainder of your factory warranty.
Anytime you start modifiying your vehicle, though, be prepared
for some headaches when it comes to warranty work. just a
head's up.
Q:
Does the Celica GT have the same suspension as the GTS?
A: Yes. The GT and GTS suspension are the same except that
the GTS comes with P205/50R16 tires on 16" 5-spoke aluminum
alloy wheels.
Q:
Can you put the GTS wheels on a GT?
A: Yes.
Q:
What are springs and what do they do?
A: Springs are mounted on the strut and lower the car between
1 and 2.5 inches. However springs have a set drop rating and
cannot be adjusted to various heights..
Q:
What are coilovers?
A: Coilovers are an adjustable spring (or coil) mounted over
the dampener. Using a threaded collar - you can adjust the
springs up or down on the strut. Raising or lowering the car,
and changing the dampening effect.
Q:
What is camber?
A: Camber is the angle of the wheels from top to bottom. The
more negative camber - the more the top of the wheel is pointed
towards the car. A degree or two of negative camber is good
for hard turns as the outside wheel is angled to take the
force of the corner and keep the car planted in the turn.
Q:
What is toe?
A: Toe is the left right angle of the wheels. Sometimes the
rear wheels of other cars are placed "toe in" to
make the car more stable at high speeds. Where the left wheel
is turned right a degree, and the right wheel is turned left
a degree.
Q:
What are camber plates?
A: Camber plates sit at the top of the strut, and allow the
strut to be adjusted in several directions. Changing the attitude
of the wheels. You will also see the term pillowball mounts
used when discussing camber plates.
Q:
What is understeer?
A: Understeer is when the car plows into a corner. The wheels
are turned, yet the car is still going straight.
Q:
What is oversteer?
A: Oversteer is when the rear of the car swings outward towards
the corner. This is also known as "tail out" and
"fish tailing".
Q: What are the dirrerences between the GT and GTS brakes?
A: GT has Power-assisted with 10.0" ventilated front
disc/rear drum . GTS has Power-assisted with 10.8" ventilated
front disc/10.6" solid rear disc
Q:
Can I replace GT drum brakes with GTS stock rear discs?
A: In theory yes, but no one has tried it and probably would
cost more than it is worth.
Q:
How do I paint my calipers?
A: You need to buy either high temp engine paint (1500 degree)
or laquer paint like Folia Tec
Q:
What is rotor warping?
A: When the rotors cool down very fast from a very high temperatures,
the rotors loose their original shape and warp. It is due
to the same reason why a very hot glass will shatter if you
pour cold water on it.
Q:
What do stainless steel break lines do and are they worth
getting?
A: Stainless steel lines simply do not expand like the stock
rubber hoses under extreme pressure when you press your break
pedal. When the rubber hose expands, you waste some of the
pressure in your breaking system and therefore loose some
break system performance..
Q:
What are vented brake rotors?
A: Vented brake disks are hollow on the inside. They look
like a sandwich and allow air go inside of them, therefore
cooling them off. Remember, the cooler your brakes are, the
better braking performance you get.
Q:
What are slotted rotors?
A: Slotted rotors have slots on their surface. These slots
provide additional surface area which help dissipate heat
better and also clean the pads. The rotors can cast slotted
or slotted after they were made. Cast slotted rotors tend
to last longer and be more cracking and warping resistant.
Q:
What are cross drilled rotors?
A: Cross drilled rotors have numerous holes drilled in them
in a variety of different patterns. These holes help the rotors
to cool better and weight less. Just like the slotted rotors,
they can be cast drilled or drilled afterwards. In general,
cross drilled rotors tend to warp and crack fast that plain
or slotted brake rotors.
Q:
What is the difference between the horsepower at the flywheel
and at the wheels?
A: At the flywheel horsepower is always higher than the wheel
horsepower. When the power is being transferred from the engine
to the wheels, so of the power gets wasted in the drivetrain
moving parts, such as the transmission and differentials.
So, the wheel horsepower is the power that actually made it
to the wheels. AT transmissions loose more horsepower than
the manual transmissions due to the increased number of moving
parts.
Q:
What type of bulb does Celica have in the High Beam headlights?
A: 9005.
Q:
What type of bulb does Celica have in the Low Beam headlights?
A: H7 Halogen.
Q:
What type of bulb does Celica have in the foglights?
A: H3 Halogen.
Q:
What is the Butterfly Valve modification?
A: The "butterfly” is a plastic part located inside
the air box that is recognizable by the small white flap in
the middle. This is a very minor modification which has not
shown any significant power gains but results in a deeper
sound when accelerating it was placed there by Toyota to help
MPG by reducing the amount of air that enters the engine &
to keep the car a little quieter at RPMs below 3500.
Positives: Deeper Sound, Little Bit Better Acceleration
Negatives: Possible Harder To Start Car
Q:
What is the S2000 antenna?
A: The S2000 antenna is a short black rubber stock antenna
on the Honda S2000. You can use this to replace the original
tall metal antenna the Celica comes with. You will have the
same reception as the stock antenna. This is a cosmetic modification
only. Part #39151-S2H-EO1. Order from any Honda parts dealer.
Q:
I want to get new rims/wheels, what is the bolt pattern and
offset for the Celica?
A: The bolt pattern is 5 x 100 and 39mm offset.
Q:
Why are Celica aftermarket parts very few and far between
than other car's aftermarket parts?
A: Because 7th Gen Celicas are still new and it takes awhile
for R&D.
Q:
Does the GT-S come with the "Super-Strut" assembly?
A: No, the "Super-Strut" is exclusive only to Japan's
version of the GT-S.

--------------------------------------------------------------------------------
The chassis is an adaptation of the Japanese Vista's all independent
suspension. The front MacPherson struts are located by pressed-steel
lower L-arms, which are attached to the rigidly mounted subframe.
The top 2ZZ-GE-powered model features the Super Strut suspension,
which is exclusive to Japanese Celicas. The suspension employs
dual forged lower arms with double joints that locate the
upright's lower end and a camber control rod that connects
the strut end and the No. 1 lower arm. The lower arms form
a virtual kingpin axis closer to the tire's contact center,
and the camber control rod reduces the tire's camber change.
At the rear, a "double wishbone" suspension has
replaced the previous strut type. The lower L-arm comprises
a tubular front arm and a pressed-steel flexible rear link.
The L-arm and a single upper link form double wishbones. Coil
springs and shock absorbers are mounted concentrically on
the tubular lower arms at their mid-length. The arm layout
and bushing characteristics provide a toe-control function,
inducing a stable toe-in during cornering and braking. The
suspension also incorporates anti-squat and -lift geometry.
The arms are attached to a hydroformed I-shaped subframe,
which is rigidly
mounted on the body shell.
