LS7 Swapped Apex Hunter – Brad Yonkers

Year: 2002

Paint Color: Torch Red

Date Purchased and location:  June 2014 – MI

Modifications and History: 

 The only modifications at the time  of purchase were upgraded  Z06 shocks// Hotchkis front swaybar// Corbeau seats and a Brey Krause Harness bar.

Initial goals for the C5Z06 was to have a fun and enjoyable platform that didn’t require modification.  That sounds great on paper but we are automotive enthusiasts and there is ALWAYS room for improvement. 

Brad’s words :

Eventually I wanted a bit more brake life as I’d burn through stock brake pads every track day. Then I wanted some better suspension, then I needed bigger tires to better use the new suspension, then the bigger tires lead to high enough G forces that the stock LS6 starved for oil at Gingerman in June 2015 and spun a bearing, a new motor was sourced with a bit more power, the extra power wound up needing a better transmission and that brings us to the current mods list :

Future plans for the car:

The car is undergoing an engine rebuild now with a different cam spec and a bit higher compression. After that it’s back to getting as much seat time as possible. Eventually I’d like to play with a few more aero mods.

As far as events, for 2016 I plan to Visit Circuit of the Americas in Texas with the Ultimate street car series and hopefully earn an invite to SEMA and the invitational again. I will also be attending as many of the Gridlife Time attack events as possible and my friend and soon to be co-pilot Ryan Finch and I will be campaigning the car in most local/national SCCA Autocross events in the new CAM-S class including the National championship. I also plan to attend One Lap of America 2017 after watching my friends from RS Motors compete for the last 2 years I’ve gotta try it!
