Tuner Comments:
This is the F430 Stradista. You'd think Ferrari would've given up on the 430 now that the 458 is out, and you'd be right; this car has no actual input from the original manufacturer. Why? They like to build fat cars, we don't. Everything has been either heavily lightened or removed, including the electronic garbage which previously polluted the car. The result is a car that, while only slightly more powerful than the 458, wipes the floor with anything and everything Ferrari's ever made.

I originally purchased a Scuderia for the first of the Ferrari events in the A-Spec ladder. I thought about the 512BB but figured I would get better longevity and use from the Scuderia further through the ladder. It did end up serving me quite well for the Ferrari and Italian events, even a few of the early championships with just a few parts modifications.

When I went in to tune to RJ's Stradista specs I already had the exact parts and needed only to change the tires. Since I am no good at dialing in settings I end up as more of a parts tuner piecing together aftermarket parts to get a car to suit my driving style.

My Scuderia was built to keep up with a pair of Enzos at Monza for one of the seasonal races I believe. The track is fast, sure, but not much in the way of difficult cornering comparatively. That being the case I took my parts tuned stallion to SSR5 for a better mix of corners and room to use the power it possesses.

It handled most of the course well, fast on the straights and quick through medium to high speed bends but a bit unstable. Braking was hairy entering the tunnel and coming into the hairpin. Exiting corners could also be a crapshoot with the tendency to snap out the rear under hard acceleration. On an MR with my Sixaxis I considered that a fact of life.

After tuning the difference was not night and day but noticeable for sure. The car definitely seemed to have tightened up in the corners and felt much more stable on the brakes. It is still easy to step out the back end coming out of a corner but it seems to do so slower, with more predictability and thus it is easier to control. The biggest difference I found was in the acceleration. Coming out of the final turn on my first go 'round I put down too much power and started to slide. My ghost, already slightly ahead, got a good jump on the straight. I was able to close and pass it in short order after regaining my grip.

After a few laps I was able to get a couple more seconds down off the lap time though it is still loose in my hands. The learning curve for this one is not as easy as Juliet, but with the higher power I expected that to be the case. Speaking of power, I found that with the parts and tune exact I was still coming up about 40hp higher and around 20 extra ft-lbs of torque than what was cited. I don't think I'm that far off on mileage to account for the difference but maybe I'm wrong. In the grand scheme I don't believe it would make a big impact on the tune, even at a 5-10% difference, but it will make it just that much more difficult to get used to using.

While I am not as high on this one as I was with Juliet, since the difference seems less significant comparatively, I definitely would give it a thumbs up. I think going back and forth between the two cars will help me as a driver to refine my skills in general and certainly with the MRs that like to try to kill me in every corner! Another job well done!

Tuner Comments:
Just like you, I hated how the 111R handled in the Top Gear special event. So when it was time to buy one for my own needs, I decided to make an Elise that would restore everyone’s faith in it. 

So this is Juliet. She may be cute, but she’s also insanely fast. There’s no ridiculous sliding or lack of braking control here, just pure grip and the confidence to use it. She’ll beat cars with twice the power and embarrass high end supercars around the twisties. If she doesn’t restore your faith in the Elise, nothing will.

How she got this fast? Well, she spent all day playing kiss chase with the NSX-R 3rd Anniversary. Sorry Romeo.

Someone call up Shakespeare to write me in as Romeo...I think I love Juliet!

As someone with decent skill at best and who uses the Sixaxis rather than a wheel, I tend to steer clear of MR machines. I find I lack the finesse required to keep them in line using just my thumbs. That said, I spent a good chunk of time on the Top Gear Test Track trying to win gold in their intermediate event and plenty of time with my own "Saffron Devil" in the British Lightweight events as well. The devil is good friends with every cone and wall in the UK, let me tell you!

Originally I had wanted to use her for the current seasonal at SSR5 but she is a bit too trim for that. Rather than ask her to put on weight, she sat in the garage watching, waiting, biding her time to show me the results of her makeover. It was quite worth it.

Confidence-inspiring has never been a word to describe an MR in my world, for previously mentioned reasons. Fear and anxiety, sure. Confidence, not so much. Until now.

Juliet and I had our first date at the TGTT and I've never before had the pleasure of driving an MR quite this well behaved in the corners. Previously, if I did not come in to Chicago annoyingly slow I would end up sliding tail first into the cones or, at best, hanging my rear end into them. Juliet attacks much quicker and with exponentially more control. She will stay planted at a much higher speed and if she does start to kick out it is much more gradual and easy to control; a quick tap and she is back on target rather than floundering around seeking grip. Oh sure, she will still slap you around if you treat her badly but if you are thrashing her hard enough to get to that point you probably deserve it. I did find her to be slightly twitchy in the straights and I am not sure why. I did eventually work that out and we were able to get in sync.

Coming off Hammerhead and down through the tires was almost an otherworldly experience. Back when she was the "Saffron Devil" I had to bite my lip and hope I could make it through without finding the grass and the invisiwall beyond. With her maturity she was able to fly gracefully through slowing only slightly for the last two corners.

And the sound...intoxicating! She is the complete package for me, both aesthetics and performance: a bit of aggression with just enough refinement. The conservatively dressed librarian with the wire-rimmed glasses and hair in a bun who lets it down cliff diving on the weekend!

All in all it was a heck of a first date. She has become quite the lady, less the demon to me than she will be to the competition. We managed a 1:15.2xx in a scant 10-15 minutes. Perhaps not her full potential but with my current skill level still quite good I think. As much fun as I had on this drive we are certain to spend much more time together learning and becoming a well-oiled machine if you will.

Thank you much to Roj. Fantastic work on this tune! You've set off a spark and gave me a smile with this one. I am eager to try more!

A quick check though. Are the alignment settings intended to be for toe out (in-game negative, as shown)? Not questioning your experience, of course. Just that I see more talk of setting toe in than out and I wanted to be sure. Again, thanks for the fun.
