NISMO has achieved compatibility between enhancement of engine output or
response and excellent exhaust gas purification performance through
leading optimal balance a between air flow resistance and exhaust pressure
and exhaust gas purification performance.
NISMO have employed the Nano-catalyst technology of Nissan
in the cell purifying device of the front catalyzer. Heat cohesion inhibition
effect of precious metal (rhodium) makes possible high exhaust gas
purification performance that is resistant to heat deterioration. In contrast
with competitors' products, NISMO after-market catalyzers maintain standards
inspection-clearing performance for a longer period. In addition, Nismo
catalyzers achieve reduction of exhaust pressure by thinning the film of
front catalyzer cells and straightening the sub-muffler.
Moreover, because Nismo took into design consideration matching of standard
ECM as well as sports resetting by NISMO, Nismo catalyzer can be used securely
without catalyzer replacement related troubles such as lit warning lamps.
Because Nismo catalyzer comes packaged with various non-reusable sensors
(Nissan genuine parts), it can be installed without additional components.

GT L.S.D. Pro Carbon is specially developed as a wet type differential using carbon fiber cloth
Features:
GT L.S.D. Pro Carbon is specially developed as a wet type differential using carbon fiber cloth
Made to run in an oil bath, the interior discs were coated with a specially
developed carbon fiber cloth. The protective qualities of the oil
guaranty superior durability and reliability. Managing oil changes and
checks is exactly the same as with any other clutch in the GT L.S.D.
series.
Otherwise, this model works exactly like the GT L.S.D. Pro and has all
the same functionalities. *1
*We have done extensive research and development to ensure that any sludge
that comes from the were of the carbon fiber facings does not have any
significant impact on LSD operation, its related parts or oil.
*1 This unit is set for 2-WAY use only.
Initial torque setting of 6kgf.m
The carbon cloth facings of the GT L.S.D Pro Carbon have been
manufactured to meet NISMO's high standards for durability. Significant
testing of the LSD series in grip races has shown that 6kgf.m is the
optimum level of initial torque for even LSD operation. GT L.S.D Pro
Carbon's initial torque is set to LOW (approximately 8kgf.m)*1 at the
time of shipping. If usage leads to the initial torque's falling below 6kgf.m,
the setting can be changed to MIDDLE or HIGH to preserve the
standard level of initial torque without disassembly of the LSD unit.
*The carbon facings employed in the GT L.S.D Pro Carbon were designed to
produce an initial torque of 6kgf.m Even when the MIDDLE (approx.11kgf.m)*1
or HIGH(approx.17.5kgf.m)*1 settings are used, the initial torque will
settle at 6kgf.m after about 100km of driving and remain stable there. Since
aware that "pushing" the initial torque will result in excessive wear to the LSD
and shorten its lifespan.
*1 Values at time of shipping are design standards.
Smoother LSD Operation
Because of the superior friction to velocity efficiency of carbon facings,
stick-slip is limited while power and operational stability are greatly
improved. With an LSD performance that is smooth from the start,
excellent oil viscosity is maintained and LSD operation is little effected
by tire wear or road conditions.
Ideal for circuit time attack or street use
This LSD's operation was perfected to deliver the maximum grip
needed for circuit racing. It will give you superior traction whatever the
tire or road conditions. The great stability of the GT L.S.D Pro Carbon
"2-WAY" also makes it ideal for normal street use, where road
conditions can be poor and where too powerful an LSD can actually
reduce efficiency. Compared to the GT L.S.D. and the GT L.S.D. Pro, this
is the best choice for street use.
Diff type (axle): GR6
Final ratio: 3.700
This kit includes following NISMO or Nissan OEM parts:
-Side flange x2
-Side bearing x2
-Oil seal x2
-Bolt x12
-O ring x1
-COMPETITION OIL type 2189E (75W140) 1L x2
-GT L.S.D.Carbon sticker x2
FRONT L.S.D. for NISSAN GT-R (R35) is developed to facilitate smoother corner entry in line with
the cornering improvements gained from installing "GT L.S.D. Pro
Carbon" or "GT L.S.D.". As initial torque is set at lower level, chattering
noise is not generated.
Cam angles: Drive side / Coast side: 45 / 1
Number of plates: 16
Initial torque: 29.4Nm(3kgf.m)
Including Fitting Kit (Oil seal, O ring, Gasket, 2x Bearing, LSD oil 2L)
To install Front L.S.D., scraping transmission case slightly is required.
Please use with GT L.S.D. Pro Carbon（38420-RSR50) or GT L.S.D.（38420-RSR52).
