After the front of the griff getting very light on the front end in the 3 figure bracket.. Have now installed LOLA style front splitters each side of car






Measuring took a while and a 15 degree angle was made in tape were to cut the slot

Have they made any difference then ? I'm not sure they would make that much difference as they're relatively small, but I'm sure it will depend on where the most significant air flow off the front of the car goes.

Aesthetically . . . Each to their own, I don't imagine they'll suit the front of a Griffith particularly, but I'm a traditionalist.

I also don't suffer alarming lightness at three figure speeds, no more alarming than my Golf. In fairness, I drive fast, but even I'm rarely properly into 3 figures.

Johno.. agree not a purist thing. they will defo make a lot of down force im hoping not too much.
I Have done my home work on racing car & 15 degree angle seems the way to go. The splitter you can see on the floor you will only see about a third of it as most slips in the cut and then formed in with fibre glass,
Hoping not to much donwforce as i dont wont to touch the back of the car spoiler wise.
The car has fully adjustable gaz golds , So i can adjust the front stiffer if need be.
Trial & error...

did you mean splitter or, what are usually referred to as "Dive plates" like these above my full width splitter?


If you do, then i can comfirm they make a BIG difference, so much so that when combined with my splitter i am having to fit a rear wing to neutralise the downforce on the front (for track use only tho).

Thanks for feed back.. I must say never heard of dive plates but never too old to learn.
had a look at your car & yes they look the same. but mine but mine arnt on such i steep angle..
Love the look of your super charger that the next step. I have a corvette with notros & not really impressed so the griffs getting supercharged...

I have a rear diffuser (see SC Power website) fitted but about to fit an ali Dual element wing
which will be easily removeable so only on for track days. I'm just waiting for the custom made boot reinforcement frame/mounts to be finished and fibreglassed in. I'll post pics when its done.

looks good and a nice job. I will interested to hear how it improves high speed turn in and front end grip on a track.

BTW have you looked into rear splitters/undertrays to get the rear end grip to match? I believe that my car has negative pressure lifting the rear at over 80mph (if the boot is open it lifts)

Front end is sorted as far as i aware,, far few rate of knotts out the week end,, no lift at all or vague steering. rear seemed fine but might look in to rear defuser...

I fitted a fairly substantial splitter not so much to reduce front end lift but to reduce drag and therefore improve straight line acceleration. Making the air turn up and over or round the car rather than under it should result in less drag and less lift. After fitting it the rear started lifting noticeably at around 90mph. The fact I only noticed it after fitting the front splitter suggests TVR got the aero balance about right. A fairly modest spoiler grafted onto the boot lid got the balance back. The Aero gurus tell me that tests often show that up to a certain size rear spoilers often reduce lift and reduce drag where a wing will definitely add lots of drag if it is going to have any effect.

Not entirely convinced about a rear diffuser on the Griff as unlike a lot of production cars the boot floor is already diffuser shaped . The swan neck exhaust pipes can’t help the air flow at all and are really easy to convert to straight alternatives.

Definately need staight exhaust for it to have any effect, and in my case you only really notice it in the high speed corners above 100mph (on track).
Although the underside of the boot is sort of venturi shaped (a little) it stops well short of the rear apron so turbulance will knacker any effect it may have had, and it needs additional straightening vanes to have had any noticeable effect imho.

I was just looking back at this thread and noticed they are different from the sc-power ones. Where did they come from?

Thanks,
