Are you planning to go to the Nov 4th Golden Gate Lotus Club trackday at Laguna Seca? I think I'll be there and would love to see what you decide on suspension -- maybe I can even grab a ride with you as I've been thinking about the Penskes for my car at some point. (I keep telling myself when I can run sub 1:50s at Laguna on the OEM base suspension, then I'll upgrade.)
Nope, the timing just doesn't work out. I'm doing Hooked on Driving Sept 26/27. This will probably be the first/last track event I do in 2015 (aside from driving the Shelby GT350 at Laguna last month), but I plan to do three or four events in 2016.
I'm going with 46mm single-adjustable Nitrons with 450/600 spring rates. This is what Suspension Performance does for many of its cars. Per what Eric of Suspension Performance shared in an email: "The 46mm are slightly more compliant on the street. For the spring rate, we use soft springs -- 450 lbs front, 600 lbs rear. We have that on both our Lotus Cup race car and so far we won every race we finished this year. The chassis is very rigid and the car likes suspension compliance."
Obviously, there are a few coilover options out there. But I know I don't want the complexity of double adjustables, I "save" a bit of money with the Nitrons, and two people I know and trust (Eric and Robbie Montinola) see a lot of satisfied drivers with the Nitrons. And let's face it: I still can't wring out fastest possible laps from my base suspension, so regardless of which package I get, I'll still have a long ways to go.
As for Vantage's comments, I use those Ferodo DS2500 pads on my Elise and they are a good street/track combo pad. Not noisy, some dust, good braking performance. Probably a little better than OEM or the same, but the OEM brakes actually aren't too shabby.
Definitely get a baffled oil pan installed ASAP though. I went with the gPan3. I'm sure Tony at TC Designs can install one for you with no problem. Those guys also modded my OEM seat for harnesses. Good folks.
I still have fresh sets of Porterfield R4s -- so that's what's going on the car! Tony did my harnesses as well (Lotus sports seats, modded for the anti-sub strap). It's good to see he's still doing that mod.
I'm still not sold on the necessity of the oil pan. But I will discuss with Suspension Performance. For what it's worth, when I stopped tracking four years ago, the oil pan mod wasn't quite so popular. (Though the fuel starvation problem was a big issue.) Have there been a lot of catastrophic engine events in the last four years?
Oh, one more question for everyone: Any new developments and fixes for the "ice mode" problem? I was one of the afflicted, and just learned to cope with it. But if there's a legit fix (other than disabling ABS), please share. I've done forum searches, and it's really hard to sift through the information. My ice-mode issues cropped up after switching to 15/16 wheels and RA1s. But maybe the wheel/tire change was incidental, and ice mode was more a function of simply faster/harder driving.
