@@desirefusion532 Carpets and interior are all impractical, they get wet, dirty, and wear out. When i stripped my CRX down to bare metal with a single plastic racing bucket and did a stage 1 NA tune, weighed under 1000lbs, it would float over rough stuff and fly like a WRC car over cattle grates at full send, and you want practicality? I can hose out the 50-100lbs of desert i pick up in the form of cowshit, dust and gravel during a drive. I was a rollcage and a few other mods away from passing tech for rally when a drunk driver t-boned me and wrecked it.

This comment sums up very well the overall feel of this series, reminiscent of old top gear but with enough personality of their own to feel fresh and new.

[@TrevorDennis100]

When you look at how cringe making bad the American version of Top Gear is with it's huge budget and C-List celebrities, you appreciate just how well theses lads are doing. The banter feels real on this channel, but so obviously staged and false on TG America. Together with Driver 61, Scott's channels are also way more informed and informative. The Formula 1 analysis is especially good.

[@Renee_R343]

I think Car Throttle is pretty good as well. Also reminiscent of the old Top Gear. 3 Brits doing shenanigans with cars, all sorts of challenges and some pretty good banter as well.

Love this! Hope they do chassis stiffening (poly bushings, motor mounts, sway bars, etc.) as well as those brakes lol

[@OxxidCZ]

doesn't help times as much as it improves the driver's feeling. Also it's much more important on higher speed tracks.

[@akaSUPERMAN]

@@OxxidCZ it seems like this track has more twisties (I wish they had done a birds eye of the track layout). But they are relatively cheap options to get the car as flat as possible, esp because most things power related, like injectors, rails, tune, turbos, cams etc will be pretty expensive ...

[@turbo_brian]

Front lower control arm rear bushings in poly or delrin will improve grip significantly. All others will be marginal improvements at best.

[@akaSUPERMAN]

@@turbo_brian that's true, except if the stock rubber is trashed, which is pretty common in older cars. Then it'd be worth it

[@hzozafar]

Super happy with your tire choice!! If you are doing brakes next, please for the love of god don’t but a big Brembo brake kit. Big brakes only help with heat dissipation, letting you get full performance lap after lap. If you’re only doing a few laps, get some quality fluid and track pads, like carbotech xp24s. Will squeal really loudly below 300 degrees but when warm, they quiet down and BITE

[@howarddavies136]

A bbk with opposed piston calipers makes a huge difference to pedal feel and confidence, so you can modulate better and trail brake for longer. Its not just about heat dissipation.

[@liam14452]

Larger brake disk means the pads have more leverage to stop the wheel which means more braking force…

[@turbo_brian]

You can most likely get enough braking torque from the stock caliper to lock up the wheels, aka the maximum braking torque you can use. Even those grippy tires can still be locked up most likely. An aggressive pad compound and a quality rotor is all thats needed. Centric 125 series high carbon rotors and hawk hp + pads would be my recommendation if available.

[@vr6one]

They can't focus too much on braking. Brakes alone aren't going to solve their 6 second problem and they can easily eat up 3k in a brake setup. The op is right, pads, better rotors and fresh fluid will be enough for a single lap. This is a sprint not a Marathon

[@howarddavies136]

@@vr6one you're right. On this budget and for this purpose, a BBK is probably overkill. If I was in their shoes, I'd probably do pads, a flush and maybe braided lines. I suspect the best improvement will be when they inevitably strip it.

Here's some insight from racing the wrx platform. Try 2deg - front camber for less understeer and when you will get to max grip in cornering you will loose oil pressure 😞

[@luckieluna]

[@rustymustard7798]

Adding lightness is going to be the ultimate mod, stripping the interior and anything not essential will do more to make it come alive than all other mods, and it's basically free.

It's nice to be able to hose off the interior when it fills up with rocks and dust from the desert. You want it to be a 'supercar'? Lambo uses skateboard grip tape on bare floorboards and CHARGES EXTRA for the 'lightweight' option of no carpet or headliner.

In california we call the nankang an "entry level all season tire." Last time I checked the rival 1.5s was the fastest on the market but that was before the new re-71rs was widely available.

[@VeliRajasaar]

Yokohama Advan A052, Falken RT660 and Nankang CR-1 are the best-in-slot 200TW tires now, also faster than the AR-1 in this type of setting because their optimal temperature is super low and they work right away from a standing start :)

​@@VeliRajasaar A052 is a qualy tire. Least durable 200TW, but fast. RS4s are great.

[@christopherjohnston6343]

Calling AR1's an entry level all season tyre is a bit of a stretch. Potentially you're thinking of the NS2r? Regardless they're still a decent cheap performer. Maybe not on the same level as AO52s etc for autocross though

[@HotwheelsReviewsGuy]

Great series however I have some suggestions. Is there a way you can use a more accurate method of timing the laps. Pressing start and stop on your phone is bound to cause incosistencies due to human error and reaction speed. Another is that it is proabably best to do a run of 3 or so laps and take the average as the result you go by.

[@verma.shaurya]

I had these two exact thoughts!

[@loickl]

Better setup of the BCs, alignement, lighter wheels, good fluid and pads with possibly some weight saving inside would do well imo

[@SpeedFreak0122]

Weight reduction, bushings and brakes will be a really interesting video! Great series

[@MaxXxoUh]

I think one of the big advantage of the supercar is the surface contact between the tyres and the road, because they're super wide. There is a reason wide body kits exists and it's not for cosmetics. It's always impressive to see the difference between LeMans GT Porsches and stock Porsches. You should have gone for wider wheels when you bought better tyres !

[@pogtuber5146]

would have required wider rims, it really wouldn' thave made much of a difference as they're not going to be doing wide body stuff

[@Appletank8]

If the wheels got wide enough, would it technically become an open wheeled car?

[@MaxXxoUh]

Ahahah Appletank8 it would need the inner part of the wheel to start outside the body ! But I think the definition of open wheel car is up to subject, as some people argue it should be single seater, or on the contrary some argue a KTM X-Bow is open wheel while it's still contained in the body. And Pog Tuber, the whole point of my com was to get wider rims and wider tyres, and yes I expect it'd have made a lot of difference especially when they're happy with 3s gain with these thin wheels

[@VeliRajasaar]

That's a common misconception right here. Tire size is pretty much only for heat management, the contact patch doesn't change all that much after a certain point.

[@bakedbeings]

Aafaik the extra width is to spread the force+heat over more area, allowing the tyres to survive (a bit longer) the abuse of a powerful engine and hard braking. In a single lap a wider wheel might well suffer from being too hard to keep at ideal temps.

[@stickybuds05]

this exactly the kind of stuff you want to see from a car channel. great comparisons, great content, looking forward to see the development of this humble wagon

[@chocosmith2243]

Brakes and tyres similar to the slicks used in this episode gave us our biggest difference in racing. Then weight. Power, bushes, suspension, etc, were very minor

[@BlakeEM]

I would have loved to see the sport tires with lower pressures than recommended, that is likely how they would be ran at the track anyway due to the extra heat, when compared to street driving, causing higher peak pressures.

Sway bars and strut braces next! No idea what the Subaru aftermarket prices are like or how stiff the chassis is from factory, but for my Volvo you'll have front and rear for €500. Before I installed sway bars I wasn't sure how much difference a thicker squiggly line under my car would make. It makes quite the difference! It doesn't mount the curbs as easily anymore, although that downside is overshadowed by the amount of grip you gain. Adding a strut brace allows you to get the most out of it. My Volvo was pretty flexible from factory, so again, no idea what it does for a Subaru.

[@vollcare4076]

The Bridgestone Potenza Sport are Great fast tyres - yes. BUT: they really wear a lot once driven hard (on track), so that’s where the AR1 shines: You can drive the AR1 really fast for a 20-30min stint, the Potenza Sport will get soft after 5-10 minutes and wears a lot

[@davidpardy]

The biggest test of budget vs expensive tyres is in wet weather road driving. I've driven some great budget tyres that still hang on to the road in the wet, but if you go too cheap they'll just slide, which is what you don't want!

Well I'm struggling to see where another 6 seconds is in that unless you get real busy with the weight loss. Power might get you something like a couple of seconds if you're lucky but really I think rubber is probably the most effective mod on that track. Maybe chipping at it will add up but I think you're into smaller gains from here.

2 years ago, I cut my rear tires on bad pavement. I drove a while before I realized something was off. My Maserati has 21 inch wheels and expensive tires. Michelin Pilot Sport 285/30 ZR 21 were over $600 x 2 USD. Messed up a rim, repair $250, oh yeah, tow on flatbed to tire shop $150. Total was too much, but had to be done. Enough rubber on front and rear to keep car from sliding in hard corners. Only way I can 'burn rubber' accelerating is if pavement is wet. Tires, wheels, shocks, brakes, suspension all upgraded to very high performance levels. It will scare me before it reaches it's limit. Would love to take it to track and actually open it up.

[@zloezlo]

You have to pre-heat semi-slicks as they have no grip when cold. With your 1-min lap you should do at least 2 heat laps and only then go for the fast lap. Also pressure needs to be around 3 bar when you finish the fast lap.

[@chrisgoudy1954]

Cool series guys!

[@Dutchboysracing]

Another huge difference will be the amount of abuse the track tires can take vs the others. Sure it's only a bit faster on a lap or two, but I would love to see the numbers after eight or ten laps. I have a feeling the street tires will start adding time a lot faster than the AR1's. Also you're using a AR1, a CRS (CR1) would be a bit quicker as its less of an endurance tire than the AR1's. That means your peak lap time would be lower as the AR1's are more meant for endurance racing.

[@benoitsauriol3140]

Something I can't figure out why they haven't done already is to put it on a diet by removing everything you don't need on a track (passenger seats, car interior, radio and speakers, AC, etc). It's basically free, you can even resell some of the parts you remove, you get a better power to weight ratio without even touching the engine, get better braking and handling, just by not carrying unnecessary weight.
