I'm a 2ar-fxe spyder owner, hello :) If your bhp figure isn't accurate, e.g. those dyno figures over read your power, then right now your ballasting yourself to slow down the horse power you don't really have. A really good idea would be to dyno it at a few different places and see how the power figures compare. Ballasting for power you don't will make you very noncompetitive indeed! Mine only makes about 166hp at the wheels, and 200 at the flywheel. Its a fast car though, 13.3 second quarter mile on road tarmac and 4.45 second 0-60.

It would have been interesting if you did some acceleration and braking tests before and after

so much negativity in the comments on this one, i know the gridlife/track thing spoiled the final look of the car but it’s the journey that makes it special in the first place. Don’t let people be negative behind their screens and keep doing what you’re doing!

Ben Lin's sense of humor is underrated.

Add an aerodynamic undertray! Free top speed, reduces lift and adds weight at the lowest possible point of the car!

For a quick and dirty way to achieve the regulation demands that does seem like a good plan in the limited time frame.but i would do things a little bit differently instead of just directly adding ballast. 1- Since the rules consider the peak HP i would try to work a new tune with lower timing in the peak of the hp curve to have for example a constant 215hp in the rpm range you are gonna race instead of a 230hp peak. 2- Considering the car gets weighted with the tank empty instead of full in combination with #1 since e85 is not only has a higher density in weight but a lower density in energy going back to gasoline would allow you to run less fuel and most importantly less weight during the race and that's important especially when you consider as said before fuel weight does not affect the minimal weight. 3- Although the car has a cage already if you are already adding weight why not add it in the form of chassis bracing to improve rigidity as a consequence at the end of the day as much as the zz30 chassis is great it still is 25 years old so every bit of bracing is better that gym weights and if it is connecting points like sub-frame/suspension mounts an the bottom of the car is pretty much the best place to add weight. 4- with everything done as great as the single ballast mount looks great you are still raising that weight rising you center of gravity so bolt those to the floor and in two places for the lowest mounting location possible. and those are just simple observations without reading or knowing anything from the rulebook if you guys really wanna be competitive im SURE there is a lot more that can be exploited

I feel like if you want to run 230whp, you'd want to use a 260whp capable engine (or more, depends on what the torque curve looks like) and detune it so that the peak power is the entire duration of the usable RPM range when shifting. In this case, unless there are rules to prevent this, wouldn't it make more sense to run this engine at 200hp, keep the additional weight out of it, and flatten the power band to ensure that you're at that 200hp peak for the entire upper RPM register or at least as much as possible? DBW makes this really easy and it seems like the obvious choice, because otherwise you're always being penalised for the extra weight, yet only at 230whp for a very small amount of time relatively speaking.

If you ever want to push stupid amounts of power in the MR2, there’s a guy based here in the U.K. called StavTech on KZread who’s worked out swap kits for 1.8t, VR5 and VR6s with both DSG and manual. Which means you can push past 1600+ without any subframe modifications or serious bulkhead work(I say that only because it’s easier to make part of the bulkhead rivnuted to be able to remove it when you need to work on the intake side of the engine). He’s got a fairly stock 1.8t one pushing over 500 on pump fuel rn, obviously the issue with your car isnt power it’s suspension/arb/tires (or a combination of all 3) but it’s possible to make these 3rd gen MR2s fking rapid without that much work!

Depending on regulations, you could look into spring suspension of the ballast. Helps with stability, and strut/shock life.

You really need to play with your spring rates. One of the previous episodes you stated the spring rates you were running and they were basically fwd setup rates. You need some softer rear rates or higher front rates. You will keep snap oversteering with higher rear rates.

My (lighter) AW11 ran with carefully valved shocks and 450lb/in front and 325lb/in rears as per the advice of the very experienced race team/builder - contrary to what many others said or did on theirs at the time, who all seemed to go softer front than rear. The handling was sublime - pinpoint precision, virtually zero understeer yet a trustworthy and faithful rear (though it did also have a functional/ adjustable rear wing built by an ex aerospace guy), and that on relatively awful tyres available / affordable back then.

You should look into a cusco breastplate for the car. helps a bit and gives you street cred. they cost like 130 bux, helps tie the underside together

Also, I think it would be a cool idea to break down each class for grid life and explain the rules in a easy to digest manner.

Re. Adding weight - based on my experience of building a track going/race AW11 MR2 using parts from a very modified dedicated GT Class race car donor - wouldn’t you gain more (eventually?) by adding weight via: Fully seam welding the entire shell (I had mine done by a v. respected rally prep. company - literally welded all round the car & made it so much stiffer as a platform) Further adding to/ fully triangulating the cage including extensions to suspension points, engine mounts etc. (ditto, on mine) Strengthening key points like suspension towers, fixing points etc. and adding chassis braces to floor pan, strut towers (unless using the cage for that?), steering rack etc. Using bigger, heavier, stronger ball joints, fixings, hubs, brakes Then ballasting up as necessary with weight mounted to help weight distribution … rather than just adding plates. Mine was so stiff as a platform and so closely corner weighted front to back and side to side that it could run much stiffer suspension than normal (advised) and helped steering feel, precision, turn in etc. that once set up by the builders (a top notch race car builder/renovator in the Formula and Sports Racing arena) it was not only lovely to drive but was competitive with cars with much greater power. Just a thought(s)!

This is exactly how the fastest racers in GT7 PP online lobbies win. They ballast the cars up to max weight for max power in a given PP limit. The results are absurd and the PP system is rendered useless as the rewards are Immense with little downside, especially when you consider most PP races do not have tire wear or penalties.

That springrate is inadequate for a stock weight zzw30 for track duty, let alone one that weights easily 30% more than stock.

Wouldn’t it be better to distribute that weight through out, or over either the front or rear axles to help with over/understeer problems.

Another "mechanical engineer here" 🤦 (trust me man people hate that) In racing, it's usually important to keep your moment of inertia towards the center and low for pitch/yaw movements.. Adding centralized weight will do this. The weight is then shifted into the front axle, rear axle, etc. via suspension setup and during cornering/ braking. This is very oversimplified, as the mechanics are much more complicated than that and I'm missing a lot here, but in short the best approach isn't necessarily to evenly load the weight.
