Blake's 86 Grand National Buick
Any G-Body owner understands that their cars make great straight line machines but lack a lot when it comes to handling. Poor suspension geometry, lightweight suspension parts that flex and bind, soft spring rates and shocks, and ineffective sway bars all add up to a car that just isn't a G Machine. We wanted to provide better handling performance for the G-Body crowd so Blake's '87 Grand National became our test mule to develop new parts. Whether building it one section at a time or through our complete Track Time package like Blake's car has, we've got the right parts for you!
Sporting a 2" drop, the front suspension of Blake's GN includes Viking double adjustable coilover shocks with unique full coilover conversion mount brackets sandwiched between totally redesigned control arms. The upper arms are designed to help with the camber curve while both the upper and lower arms have positive caster built in. This translates to a more aggressive geometry that equals an incredible handling upgrade. Optional ATS tall spindles offer a taller profile, relocated steering arms for eliminating bumpsteer, and Corvette style brake mounts around ZR1 Corvette hubs. Also featured on Blake's ride is a heavy duty front triangulation brace and larger tubular sway bar.
Rear suspension is equally impressive with Speedtech's rear coilover conversion featuring Viking double adjustable shocks. Speedtech exclusive upper and lower Articulink trailing arms twist with suspension articulation and avoid the binding common with these cars. Frame mounted adjustable sway bar with Speedtech Articulink mounts is about 3 times more effective than the factory bar.
For stopping power the GN rides on 14" rotors surrounded by Baer 6 piston calipers. Rolling stock consists of 275 and 295-35-18s wrapped around Forgeline diamond cut and black powder coated ZX3Ps in sizes 18x9 and 18x9.5.
The GN retains the stock Turbo 3.8 V6/ automatic drivetrain and with the all new suspension upgrades this thing is an absolute blast to drive!
