After prolonged pontification, this is where I have arrived
Since I really only have one shot at this, and just 6 weeks to prepare, I've searched every Boxster racing thread I can find to get the best mod list. The rules are I can only spend 19pts.
These items have already been purchased:
-Four 17 x 8.5 stock wheels (0pts)
-Schnell camber plates (0pts)
These will be purchased momentarily:
-Four 245/40/17 Khumo V710s or BFG R1s or Hoosier R6s or A6s (all choices are 9pts) (opinions welcome... my only experience is with V700s and RA-1s)
-H&R sway bars F&R (2pts) (The GT3 sounds like too much work to get right with having to match end links to my specific setup, etc.)
-Fabricate rear chassis support (3pts)
This will get me to 14pts. If I were still racing Miatas, I'd revalve the stock Bilsteins (3pts) and add Ground Control coilover sleeves (2pts), probably copying the BSR's 450/500 spring setup and bringing the total to 19. Unfortunately, there don't seem to be any coilover sleeve options (or any other option for mounting a race spring on the stock shocks). This leaves me with just the H&R springs (which don't seem to be much stiffer than stock, so no need to revalve the shocks). Would the car be competitive with soft springs and stiff bars? Rather than rebuilding, I could just buy the Bilstein HDs, but I'm still left with no stiff spring choices.
Alternatively, I could use DA coilovers valued at <$3000 for 5pts making the total 19. I'm a bit hesitant to purchase what seems to be the Boxster owner's favorite: PSS-9s. I've dyno'd shocks while interning at Ohlins, and
DG explains my reasoning the best. The Ohlins at $2500 looks like the better choice, but no one in the Boxster community seems to use them... why is that? Ohlins makes just about the best shocks money can buy, so why no love? All of the other mods are relatively inexpensive, so I don't mind taking a chance on them, but $2500 for coilovers is a lot of money to spend when I'm not even certain the car can win and it might be back to stock a week after Nationals. And if Ohlins aren't respected in the Boxster community, I'll loose my shirt selling them.
My required weight is 2855 with driver, and I'm certain I weigh more than 3055 w/o me right now. I'm 150lbs, so that makes 350lbs I need to lose without doing anything irreversible. Where can I find that much weight?
If you have (or know of anyone who has) any of these parts listed that would like to sell them used, I will purchase them immediately... time is running out!
Please shower me with your (doubtlessly) infinite wisdom on getting a Boxster to put down one excruciatingly fast lap.
