While we touched on the cosmetic changes in part 1 of this post we didn’t delve into the more technical changes yet so here goes./ppa href="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-010.jpg"img src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-010-540x242.jpg" alt="" title="gtrblog-gtr35-2-010" width="540" height="242"/a/ppstrongAero Updates/strong/ppAero changes to the front bumper, rear diffuser and rear underspoiler mean that the 2012 GT-R slips through the air with even less drag than the already impressive 2009 model. As mentioned previously, these changes help it lower it’s co-efficient of drag as well as increase downforce in the rear by as much as 10%. The rear vents also assist in keeping rear underbody temperatures lower meaning less heat transfer from the GT-R’s hot exhaust into the critical areas like the GR6 transmission fluid and rear differential./ppNissan took the opportunity with the rear diffuser/underspoiler rear design to build in a rear Euro mandated fog light using an LED strip along the bottom edge in the center./ppa href="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-014.jpg"img src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-014-540x164.jpg" alt="" title="gtrblog-gtr35-2-014" width="540" height="164"/a/ppstrongChassis Updates/strong/ppAs well as aerodynamics, street and circuit handling in the 2012 GT-R is going to benefit greatly from some key chassis stiffening updates in the DBA-R35. Strengthening members are added to the front area under the dashboard (highlighted above). In the engine bay, new bracing members extend from the rear of the strut towers to the firewall./ppAs well as increasing chassis rigidity by adding new key metal – the GT-R engineering team has improved the manufacturing line to improve GT-R build quality and panel fit consitency for every car built./ppa href="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-013.jpg"img src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-013-540x293.jpg" alt="" title="gtrblog-gtr35-2-013" width="540" height="293"/a/ppstrongSuspension Updates/strong/ppAgain showing that the Nissan GT-R engineering team is focussing on driver feel, they’ve gone to the extrordinary length of changing the suspension geometry on the DBA-R35 model. The changes to the front suspension lower arm move the stabiliser bar further out and change the shock absorber lever angle. To go with these changes up front is a castor angle change from 5°35 to 6°00. In the rear, Nissan has tuned the roll center./ppAll around, Nissan’s update to the suspension to adopt an aluminium free piston design as well as spring, damper and valve rate changes mean the suspension is able to more quickly adapt to changes in surface and direction. The net benefit is a more stable and more responsive feel with even more feedback to drivers than ever before. /ppstrongBrakes, Wheels and Tires Updates/strong/ppNissan’s experience with racing over the past few years with the GT-R has taught them that more stopping power is always better. To that end they’ve upped the front rotor size on the DBA-R35 from 380mm of the CBA-R35 to 390mm. /ppAs mentioned already, the DBA-R35 will debut with a new design Rays forged aluminium wheel each 3kg lighter than the outgoing type. These wheels will come in two new colors Hyper Blue Black and Hyper Titanium. The new Rays wheels feature improved knurling to help further with reducing tire slip on the rims themselves./ppTo fit these new wheels are updated versions of both summer tires already being fitted to the GT-R, namely the RE070R R2 from Bridgestone and the SP Sport Maxx GT 600 DSST CTT from Dunlop. Both are touted to improve grip and increase sidewall stiffness, something very important in a heavy awd vehicle such as the GT-R./ppPart III to come soon where we’ll cover the remainder of the DBA-R35 changes including interior and engine changes, so stay tuned…/pa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/gtrblog-gtr35-2-014/" title="gtrblog-gtr35-2-014"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-014-100x100.jpg" alt="gtrblog-gtr35-2-014" title="gtrblog-gtr35-2-014"/aa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/series-ii-r35-brakes-gtrblog-002-2/" title="series-II-R35-Brakes-GTRBLOG-002"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/series-II-R35-Brakes-GTRBLOG-002-100x100.jpg" alt="series-II-R35-Brakes-GTRBLOG-002" title="series-II-R35-Brakes-GTRBLOG-002"/aa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/gtrblog-gtr35-2-013/" title="gtrblog-gtr35-2-013"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-013-100x100.jpg" alt="gtrblog-gtr35-2-013" title="gtrblog-gtr35-2-013"/aa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/gtrblog-gtr35-2-012/" title="gtrblog-gtr35-2-012"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-012-100x100.jpg" alt="gtrblog-gtr35-2-012" title="gtrblog-gtr35-2-012"/aa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/gtrblog-gtr35-2-010/" title="gtrblog-gtr35-2-010"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-010-100x100.jpg" alt="gtrblog-gtr35-2-010" title="gtrblog-gtr35-2-010"/aa href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/gtrblog-gtr35-2-009/" title="gtrblog-gtr35-2-009"img width="100" height="100" src="http://www.gtrblog.com/wp-content/uploads/2010/08/gtrblog-gtr35-2-009-100x100.jpg" alt="gtrblog-gtr35-2-009" title="gtrblog-gtr35-2-009"/abrstrongView Entire Article/strong: a href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/"2012 Nissan GT-R Leaks: Part II More Confirmed Details/a at a href="http://www.gtrblog.com"GTRBlog.com/ahrpsmallOriginally appeared on and © a href="http://www.gtrblog.com"GTRBlog.com/a. 2010. | a href="http://www.gtrblog.com/2010/08/29/2012-nissan-gt-r-leaks-part-ii-more-confirmed-details/#comments"Read comments./abr/small/p
