Good platform for stripped down gt3 car?
 

Thinking of making a stripped down gt3 car, brz or lotus?

BRZ.
Lotus got crapy weight distribution, gear ratios, shifting feel, build quality, reliability.

If you can go crazy, a Lotus with BOE TVS supercharger, EliseParts paddle shifter gearbox and all the light stuff gonna be crazy fast.

I'm switching atm from an Exige to a GT86 for the cargo space, because I wanna use slick tires.

Parts are less expensive for the Lotus, coilovers are like half the price.

If you don't need the cargo space, s2000 is the best car. In this case I would do an Evasive like build.

Lotus steering feel is the main reason to get one.
The low weight is counterbalanced by the crapy weight distribution 62% rear.

Anyway, you have to buy a NA Exige. OEM supercharger is useless and more expensive.

Is there alot of Lotus in your area? Is there a price range that you want to be in? Lotus in my area are usually around the 40k mark due to it's "rarity" .

Exige prices are increasing in Europe too.

Depends entirely on what the series rules dictate.

To add to my comment, I think this car is absolutely the worst thing to use for racing in the GT3 category.

Here's a list of the currently-homologated cars in GT3 classification:

Touring car racing, I can accept as the entry barrier (and performance level) of the cars is lower.

If you are thinking about SCCA GT3 then that's an entirely different story.

By gt3, OP means gt3 race car or gt3 like road going track day car ?

My comments were for the road going one.

Road going. I dont want to race it but i want it like a gt3 car... If that makes sense?

I'm in the same case.

If you want a lightweight (low running cost) car, you have to choose between Exige, FT86 and s2000.

The s2000 will be the fastest car for the lowest cost.

FT86 if you need the cargo space to carry track tires.

Exige for the ultimate pace, with:

BWR build engine and TVS supercharger (400hp on pump gas)
EliseParts sequential gearbox
EliseParts brake discs with OEM calipers for sprint or AP racing for endurance
Nitron 46 mm coilovers
TSW 1.4 wheels.

I don't get it o:

Yeah, that's a nice thread

Here is the Evasive s2000 :

The gearbox :

Lotus OEM gearbox is not good enough for a supercharger, you need at least the kaaz gearsets.

If you don't have the money for the build engine, you can go for the non intercooled 300 hp TVS
The TVS is a high efficiency supercharger that don't need intercooler for 300 hp. Even for racing purpose.
Stock engine is safe at 300hp

Build a spec Miata, cheaper than an 86 and over 5 seconds a lap quicker than a stock BRZ around Laguna Seca and a huge community and aftermarket available.

And then you can actually go race it for a season or two with the money you saved from not buying a Toyobaru.

I dunno much about miata, 5 seconds with same tires on both cars ?

Would be the smart thing but i want a car i like, and nothing against the miata, i just dont like it. I already own a brz

Who said anything about the same tires? We're talking about building a racecar aren't we? Sure you can go faster with an 86 if you spend some money on modding it, you'll also go faster with a C5 or C6 Corvette and even faster with a 911 or GTR. But for less than $20k you'll have a car that's faster than the >$20k you'd spend on a used 86, not to mention the cost of building the 86 to match.

And racecar

This is a few years old, this past year some of the legal guys were dipping into the 1:45 range, the illegal guys were well into 1:45. And to be clear, spec miata has the motors sealed to factory specs, we're talking about a car with ~130 horses at the crank, non-adjustable bilsteins, roll cage and sticky rubber being 5 seconds faster than Randy Pobst with a stock BRZ being timed by a magazine. With a good turbo build and some money on a high quality damper spring combo an old p.o.s. Miata would be wicked fast, might be able to get under 1:40 with balls of steel? Mclaren P1 and Porsche 918 are right around 1:30?

Then why ask? Go build your racecar BRZ, you won't be the first and you most certainly won't be the last, go have fun.

And if you 'like' the Lotus more then save up for the Lotus, see if you can test drive one before you commit to not working on the BRZ.

FT86 laptimes on stock tires means nothing to me. Even with a good driver.
Spec Miata looks like a good car.

That's the rookie car in iRacing. It works fine.
