Suspensions are obviously too soft. But 245 might be faster at this track that turns a lot.

I was limited with 225 on the Lotus, so I guess they worth it on the 86.

Next time I will be on coilovers to find out.

What spring rates are you going for?

10-12k.

Double the base spring rate looks like the absolute minimum.

Lap times were pretty much meaningless.

At track speed, the steering is fine. Not Lotus quality, but I guess it will be good with ball joints top mounts and the right bushings.

When I had the opportunity to have some grip, the ad08r were moving the stock suspension all over the place. Definitely way too soft.

They look like really good tires.

I had corner entry oversteer, not crazy, but unexpected on a stock suspension. Definitely a drift car.

Pedal dance is a pain to do. I had it right once. I drove without after that. I need that magic box to make it automatically.
Without the dance, slight ABS activation makes the driving line inaccurate.
The Ice was more of a pain than that, so I changed my braking a bit for today.

The RR works fine. That was a easy day for them. It needs more testing.

The gas pedal calibration is total journalists crap. 2nd gear was totally useless in this conditions. Feels like you have 50% torque with 1% travel.

The rain started at the end of the midday break. So I went home, missing the opportunity to shoot a video on the non icy track (sorry about that)

Even with the 1Hz GPS, Racechrono predictive lap timing worked great. That's one hell of a tool. I need that 10Hz sensor :p

At the end of the day, that's a great car with massive potential. It drives exactly like the spec sheet says.

I was really happy driving back home in the rain, not being in the Lotus on worn out a048r.

I guess I miss Lotus ABS which is faster.

The car is a lot easier to catch thanks to the weight distribution. But the soft springs make the catch less accurate.

Edit: I drove 2.22.00 for an optimal lap of 2.21.86
Given the conditions that's OK. In the dry in the Lotus on new a048r I guess I can drive 2.00.00.
The 86 might do 2.05 - 2.07 I guess. 2.10.00 is totally sure.

hopefuly this video helps you sort out suspension issues/questions you might have. subframe bushings are soft.

Thanks, great video.

It looks like my Lotus will go soon. That means more parts for the 86.

I'll try to spend around 10k€ at first.
Around 3k will go to the Nitron R3 and the trip to the UK.

I need a high end GPS receiver. Probably the 20Hz Vbox sport.

I need a tyre pyrometer and digital pressure gauge. The less expensive Longacre stuff will work fine I guess.

I need a torque wrench, a cordless impact gun and a lightweight jack.

That should leave something like 6k for upgrades.

Maybe ACE type B header + Delicious Tuning calibration and EcuTeck stuff.

4,55 or 4,67 final drive.

OS Giken LSD

Good sway bares.

Or a new set of wheels and slick tires.

What would you do ?

Why are you visiting us in the UK?

Nitron failed to find an 86 in the UK for development. I'll bring mine to them in exchange of a 50% discount and free installation.

Vbox receivers are good but expensive. You can check also the AIM receivers which are good and offer additionally data-logging. AIM Solo DL can connect to your ECU and monitor or data-log additional parameters (oil temp, water temp, rpm's, etc.) Then you can check more details about your driving.

Yes, you're right. I need to look at the DL too.

Suspension, LSD, sway bars, header+EcuTek are definitely on my list, and slicks would be the last thing i'd go for.

I'd get the TRD cross mission gear set(or Cusco's) to go with a shorter final drive.

PS: Do you know if Nitron is looking to test the R1's as well? 50% off...y envy you!

PS2: I didn't know about Longacre products, cool stuff!

Yes, the Cusco gear set looks super usefull. But the labour cost must be crazy.

I think Nitron will test both R1 and R3 on my car.

I had to cancel with Nitron because I can't cross the border at the moment. The paperwork for the car is very late.

That sucks.

I'll buy JRZ, maybe even the 12-32 crazy race stuff.

The Lotus is supposed to be sold this Saturday.

I have an order at CSG for ACE header, Delicious calibration and SPL suspensions that is ready to go as soon as I got the money from the car.

One last family shot :
