It will scrape anyway....the lowest aero bits are behind the front wheels

differs from experience with my 4RS. I forgot to use FAL at one speed hump. Scraped undercarriage. Used FAL on same spot later and was fine.

Did not think about the unsprung weight. Great point. Thanks!

That's got to be some serious speed hump....on the 718 gt4 I never had a problem with the front, but the rear diffuser did scrape occasionally. The front splitter extends further on the 4RS but not by a huge amount. IMO it depends how you use the car and where you live. As you can guess no FAL for me, like to keep it simple.

From a resale perspective FAL is sensible even though you may not desperately need it where you drive, but if you go down into underground car parks, or onto ferries, FAL is absolutely necessary on the GT4RS. 5-6kgs is nothing in the grand scheme of things.

It also makes changing tyres and adjusting front aero easier.

LOL 5-6kgs is nothing.....people pay a lot of money to remove 10-14 pounds of weight from their cars.

I dont Spec cars or save them for the next owner

If we go down the weight savings hole then why spec Mag wheels or PCCB....its only a few Kg.

Again FAL works for some but after 2 GT4s I'm pretty sure I can live without.

The resale issue is def the biggest argument for them. Is it worth $3k? That's the big question. I don't need it where I live. I drive my 7.1 RS with zero issue. But, I've learned to stay away from curbing and take inclines from the side. It is factory height. I have had it on speed bumps with no issue in a park, but it doesn't have the diffuser the 4RS has. Of course, the diffuser won't matter from a FAL perspective.

That's a great point about building a car for the next owner. That's the main reason I'm looking at LWBS. For me, the sofas for sure. I have two race cars for the track. LWBS looks great, but I really need to sit in a car with them to know. My wife hated them in the last GT4 I had. I wasn't crazy about them either.

FAL 100% all day must have option on the 4RS.

Makes world of a difference.


You can see how much it raises it compared to no FAL. It’s a good inch and a quarter.

I ordered my car for me, not the next guy. Lightweight spec, sans electro-gadgetry for me!

Well said. Same boat (but with just one previous GT4)

Magnesium wheels and PCCB together save 27 KG of unsprung rotating mass, which is much more important than the static mass of the FAL, in terms of driving dynamics: acceleration, braking, steering feel, and ride.
