I don't know, we couldn't find more time using r-comps, I think it's going to take a major change to see much more, to be honest more power seems to be the logical step. Since I can catch almost anything in the corners but can't pass once there is a straight. The megasquirt should yeild another 20 or so hp, and ebay turbo mabye 300 total. That has to be the missing 10 or so seconds

I gained most of my time by getting my brakes straight and having the alignment spot on.
Before the last event at Sebring I switched to an all aluminum coilover and had the car aligned while I stood there and directed the tech.
Also, a good friend of mine, Ivan at CFP, took the time to make brake ducts for my front calipers. It made a world of difference as the brakes were rock solid all day.
I was down on hp from the event before this last one and still ran 6 seconds faster.

Jeff's Sentra has kick-ass brakes, but I bet there's a few seconds out there we could gain by making better use of them. I'm a notoriously early braker.

Yes the brakes are more gooder I was paying extra attention this week, even on the autozone pads, I was starting my braking 10 feet later then the 911 porsches, I know I am loosing 5 seconds on turn 17. I'll be honest it still intimidates me it's just 1/2 of a flat track oval. So it's not the walls that unsettle me it's not being able to look through the turn.

Here we are.
front:
camber - -1.0 to -1.2 deg
toe - 1/16" in
caster - 6-7 deg
rear:
camber - -0.5 to -1.0 deg
toe - 0 to 1/16" in
thrust angle: zero
front:
camber - -1.0 to -1.2 deg
toe - 1/16" in
caster - 6-7 deg
rear:
camber - -0.5 to -1.0 deg
toe - 0 to 1/16" in
thrust angle: zero

Have you tried running more neg camber up front?
R compound tired usually like a lot of neg camber.
For reference here are my specs
front
Camber -4.5
toe 1/16" out
caster + 6
Rear
camber -2.5 deg
toe 1/16" in
caster 0
I am just sharing, not trying to say my set-up is better or anything like that.

I'd agree. Even if the car is driven on the street, you can get away with a lot closer to 2 degrees of camber without issue. Of course, the real way to determine what your camber needs are is with a pyrometer.

Honestly, this is the first time the car will be aligned in several years (Dropping the car off tonight). These specs are simply the recommendations of people with 3rd gen rx7's and 18inch wheels who run long tracks. The car is rarely street driven, so I could care less about tire wear. More opinions? Thanks
* Edit - I just went through several more sets of alignment specs from other drivers and no one comes close to 2 degrees camber (closest was -1.5)

Could be a limitation of the suspension design. Or it could be a "feature" of the design, perhaps it doesn't require as much static camber?
Run with it. See how it feels, maybe borrow a pyrometer and take some tire temps.

Will do. As I am a noob, I measure inside/outside/middle tread of each tire after several spirited laps? Thanks again.
