6 Replies and 1750 Views Track Modifications in Street Class   1750  6 Started by  ltborg I'm looking at doing a few modifications to my B-Street car to make it more reliable at track days. One of the things I would like to do is add the C5 Z06 rear brake ducts, which require a hole/vent in the rocker panel of the car (see these picture instructions for details).   Since the ducts themselves bolt in with a single bolt, what I am wondering is if I removed these for autocross competition and blocked the vent in the rocker and inner fender, would this be considered a comfort and ...

9 Replies and 3913 Views C7 Z51 with or w/o MRC?  3913  9 Started by  nathanprovo I have a 2014 Corvette Z51 on order w/o MRC (magnetic ride control), I have a few days to change the order, so I wanted to get any thoughts on how well these shocks/technology might perform when compared to aftermarket adjustables. I have been running a C5Z06 with koni singles for the past 10 years on r-comps.  I will likely be running the C7 in Super Street.

(Topic has multiple pages1 2 3 ... 4 )
Given the changes to street tires and some of the classing changes...voice your opinions on the dominant car(s) in each class. To start the discussion: SS - Elise...can anything catch it on street tires AS - no idea here...newer cayman/boxter S BS - C5, S2000 (likely to be very course dependent; curious if NSX might sneak in there...) CS - NB Miata Sport, FRS/BRZ seem like contenders.  Any thoughts on e36M3, or NISMO350Z DS - 3.2TT, 2011 WRX ES - 1.8 miata R FS - no idea here.....

8 Replies and 2088 Views Electronic shock electronics question  2088  8 Started by  sjfehr SCCA Solo rule 13.5 permits non-electronically controlled shocks to replace electronically controlled shocks, but isn't clear how the electronic bits are to be handled when the electronic shocks are removed, or the associated option package installed.   Where electronically controlled shocks have external electronic control units dedicated to the shocks and serve no other purpose, are they considered part of the shock assembly, with all that implies  I'm thinking they'd fall into th...

3 Replies and 1518 Views Volvo S60 T6 allowed in GS?!?  1518  3 Started by There is no way this can be right. A 6 cylinder AWD Turbo car under 4,000 lbs competing against things like non-tubro mazda6's, altima's, sentra's, and non-turbo imprezza's. Looking at the specs for the Volvo I can't imagine it being classed anything less than ES.  Looking in DS and seeing very close competitors for the Volvo like the Mazdaspeed6, Eagle Talon AWD, Eclipse GSX, Audi TT quattro makes me think it probably belongs here in DS. Does anyone know the reasoning behind this beast b...

11 Replies and 8554 Views C5 Z06 Optimal Wheel and Tire Sizes for 2015 rules  8554  11 Started by I picked up a 2003 C5 Z06 and am trying to figure out how to set up the tires/wheels for Solo 2.  I went to an event this weekend and saw someone running stock 17x9.5 F and 18x10.5 R wheels with 255/40/17 front and 315/30/18 rears with BFG Rivals.  The fronts are limited in width by sizes that BFG makes for 17 inch wheels. Since we can change wheel diameter by /-1 inch I'm thinking to buy some wheels that are 18x9.5 F and 18x10.5 R which opens up the front tire options. If I do...

2 Replies and 1324 Views DS Audi TT what to look for?  1324  2 Started by I saw that the 2008 Audi TT did well in 2013 in DS. Is there something special about the 2008, or was that just a statistics of small numbers kind of thing Anything special I should look for in one to buy I gather the 3.2 V6 is the motor to have. Many thanks for the advice. A little bit about me: I have done years of autocrossing with a 4th gen Camaro in FS, and a PT Cruiser GT Turbo in GS. We want a TT as a daily driver, AWD would be nice for snow, and it would be fun to have a shot at 1st i...
