991.1 GT3-RS: GOOD TIME TO BUY...??

To be fair you probably wont feel any difference chassis wise as its only bolted in anyway. Useful if you are tracking the car. My 997.1 CS came with the harnesses and extinguisher still in thier boxes. The original owner specced club sport but never trackd the car. Fair enough but it does seem a little weird

like wise my harness and fire extinguisher are still in boxes ;-) the car feels way stiffer and more direct than my GT4 did, I thought it might be the cage helping. maybe it's just how the car is over a Gt4. But I don't remember a 991.1 non caged car feeling as direct as my new one.

You will probably find that its the sping and shock rates. The 991 chassis is pretty stiff. you could probably run race spring and shock rates and suffer minimal distortion.

The standard non CS GT4 is one of the very stiffest cars on the road (40000Nm twisting force) compared to about 32000Nm for the standard 991 coupe..The reason for this is the open top Boxster's chassis which it shares with the Cayman was designed from the outset to have no roof.This contrasts to the 991 Cabrio which needs extra bracing to retain structural integrity.It also explains why the Boxster feels much stiffer than any other convertible yet weighs the same as the Cayman coupe.
I'm willing to bet the CS cage does improve stiffness, evident when you hear the creaking from the cage when driven hard on a track due to the body trying to twist against the cage.

Yes the seat ( 918 type ) has great retention and no need for a Harness as for track days the belt is fine and as a road car there are airbags everywhere for the safety aspect .
Race cars you need it ( will not scrutiniser without ) and on slicks the lateral forces are higher as well as a full cage has some nasty bars to bump into in an accident ... which will happen when racing .
The .2 RS runs with minimal body roll due to the stiff springs and am going to make some small set up changes to the camber and roll bar ... to start with as limited by understeer .

until you land on your roof ... then the airbags don't help much and even the half-cage can make the difference

one might say the cage saved this guys life a few months back.

I'd always have a roll cage in a car that was tracked. Much more of a roll possibility as tyres dig into grass if the car leaves the circuit. I've seen it happen quite a few times

Yes totally agree. I have ended up on my roof at Donnington when racing and was super glad I had full cage. Craner curves kitty litter, dug in sideways and over I went a few times! I find 918 seats good but still require 6 point as braking forces at work mean without I feel i’m comfortable without six point harness

The cage worked in the top pic then over a non caged car.

the red one had a cage ... it broke (you can see part of it sticking out on the right)

I must say I cannot see a cage in that pic.

mmhh fair point - not properly visible. Look at the lower corner left of the b-pillar and you can see a bent part of it.

Given my dog and I sat in it and would certainly both be dead now without the cage, I can assure you it had one

thank you - yeah lesson learned, I don't think I will be that lucky a second time. also having harnesses and not wearing them did not help - as I found out, you will eat windshield airbag or no airbag

Eak…..has it put you off cars at all ? I want a bike again but too risky to ride one now I think for me.

no, just switched to Ferraris with all the nice electronics that hopefully work and decided to stay away from Cup 1 (or plus whatever they were called) tyres on daily driven cars (and turbo engines I guess, although that will be tough to keep up going forward)

Dog ok hopefully as well with no lasting affects (as a dog person I ask)?

he was not physically harmed - although he was hanging outside the car facing traffic when I woke up after a brief nap while we were flying. Unsurprisingly, he is not keen on driving anymore as a result - he unfortunately has a good memory ...

Yes 993 rsr bit scary for the dog ( another dog lover ) . Both accidents look like high speed on public roads . Had a few Aquaplaning experiences on worn cup tyres ..
Anyway good to hear all were safe ...
