...if they are discontinued for some reason, you could either keep the Porsche tips or go for a different aftermarket carbon/titanium tip...

Thanks, Rab. Yep, nothing too dramatic, but 7mm spacers all round is what Iain Litchfield recommended and what he’s done to his own T. Hopefully it’ll get sorted with minimal fuss.
I think the difference is quite dramatic, for a 20/10mm drop! I think it looks even more amazing now :D

I think with those springs and bushes, you’ll feel a lot more texture and contrast to the ride on different surfaces and an even better feel for the contact patch. I hope?

I’d be wary of spacers though! They do look good, but generally have an adverse effect on geometry and arm control.
While a wide track can be beneficial, creating that artificially, at the end of the arms is not.

You’re essentially providing a longer lever for road forces to be applied to all suspension joints/mounts.
The wheel is further out on the arms. Even 14mm is quite a lot and this can be felt, especially under big braking loads.

I know the T suspension arms and locations are strong, but 14mm extra added mechanical disadvantage is a lot at 1G+

Have you ever had spacer before? I have and I took them off after a little while!

Thanks, Red5! :)

Have only driven it home so far, but looking forward to getting familiar with the new feel of my car. Certainly felt firmer, sportier & more 'tied down'. I like the new feel and for me, it's not too harsh. Iain Litchfield tested his T back to back with a 991.2 GT3 and said that this set up was better than the GT3 for daily driving, with the GT3 constantly feeling 'on edge'.

I've not had spacers before, but know it's an easy job for them to be removed again, if they are not to my liking.

Having test driven Iain's T, with the spacers, albeit on a fairly short test drive, the car felt great to me. He said he'd tested various spacer sizes, and concluded that 7mm all round was the best solution.

Having met Iain & some of his team, I have confidence in their work. They've been around for approaching 20 years and are well respected in their industry. In addition, the feedback from motoring journalists is great too, having driven Iain's car:

"Litchfield benchmarked a current 911 GT3 for steering feel, and so its upgrades for the Carrera T include revised front suspension geometry. Although the KW springs are stiffer by around 20% at the front and 10% at the rear, the car’s ride quality has been more or less unaffected, and the brilliantly judged damping that makes the factory-spec Carrera T work so well on our bumpy roads is carried over intact. Even on a really tricky section of B-road, the car’s suspension is pliant, absorbing bumps rather than being kicked about by them, while the body is so well tied down that you simply never feel it get light or out of phase with the wheels. It feels like witchcraft.
The steering is more impressive still. It's so pure, crisp and responsive, and the wheel fidgets so subtly but tellingly in your fingertips that it feels as though the car’s electrically assisted steering rack has been swapped out for a hydraulic one. Until there is some great breakthrough in the technology, electric steering gets no better than this.”

“Ever the perfectionist, Iain reckoned some detail tweaks to the chassis could also help, so he fitted custom springs to stiffen the front end and lower it by 20mm, while the rear is dropped by 10mm. 7mm spacers push the wheels out slightly and adjustable uniball items replace the front suspension bushings for a little bit of castor adjustment. All of this introduces a racy-looking rake but, more importantly, sharpens up the already brilliant steering by another notch, without overwhelming the all-round usability or subverting its all-rounder appeal. Matched with the stock dampers, mechanical limited-slip differential and T’s reduced final drive you have, perhaps, the recipe for the best ‘fast road’ 911 this side of the GT3 Touring…”

"And how’s the handling? It’s not as sharp as a GT3, but as a road-biased set-up it’s as good, if not better. Mean it. The damping hasn’t been touched, but it works brilliantly with the stiffer springs. It goes down a road more positively than the standard Carrera T, and you get more feedback from the road surface – it’s a more granular experience. But no less comfortable. As ever in a 911, the biggest bar to cruising comfort is tyre roar, but at least here you’re getting the information to go with it. And not just through the seat of your pants, but the steering as well. The switch to a solid bush might sound hilariously minor, but what it has done to steering response just off centre, taking what little slack there was out and introducing a bit of writhe, is a delight.

…but because the car sits lower on stiffer springs, there’s less jack-up under hard braking, less weight transfer. It’s the same with acceleration. And cornering. The car is better supported, so takes bends flat and hard, and the traction when you exit is ridiculous. I really, really enjoyed driving it.”

As you know, WingCo I already thought of the T as a GT3 junior and it seems you've taken a step towards bringing it up to at least equivalence. I'm really interested to see what you think once/if you have the remap done.

All looks positive so far and it also looks like you will make the second 100 page thread with this one!

Ha ha - we’ll see... ;)

Was going to get the remap done next, but they advised that I’d have to have the tune re-done after having had the new manifolds & sports CATs fitted, so I think it best to go the whole hog next time: ECU remap, Remus exhaust, new manifolds and sports CATs. :twisted:

Maybe it wasn’t wise to test drive Iain’s car after all...!?

The remap will give you 40 more ponies than I have in the GTS and I’ll definitely be interested in how that’s delivered through the manual box in a RWD car. The 4WD GTS can be brutal if provoked but is normally very civilised

If my car drives like Iain Litchfield’s reworked Carrera T, I will be delighted!

The only difference between my plan and his car is that he fitted the Akrapovic titanium exhaust to his, with Akrapovic rear diffuser and titanium exhaust tips. I’ll opt for the Remus stainless steel exhaust and retain my existing Porsche black Sport Exhaust tips and OEM diffuser.

The Remus is apparently a little louder than the Akrapovic, but not obnoxiously so. :P

I will of course continue to provide updates on this thread! ;)

WingCo the Akrapovic is full hooligan sound. Seriously. So if the Remus is louder I would certainly think twice unless you want attention everywhere you drive

Just one update at a time, twenty posts on each. 100 pages a doddle :D
Its great to see someone enjoying a 911 as it was intended.
