The resource of me knowing how to apply alumilite in some fashion other than a front splitter. LOL
Or to add widebody parts.
Etc
Etc.
My budget is super modest, so I'm happy with my car so far, but I'd really like to do more.
Using a block of wood or a round tube pressed against the alumalite and slowly pulling up will create the shape you desire..
So turn in and probably ultimate grip up front increases, but do you have to soften the rear to keep balance? Lower setting on the swaybar i assume?
Yup wider track in front for better grip. It all depends on the track and driver preference with the sway bar. At buttonwillow with the RobiSpec adjustable sway bar which has 4 holes in it, we have it one click below full stiff.
Here is an in car of the car with the anze suspension penske and Racefab lower control arms

i dont think a blanket statement about the bar can be made. i have whiteline bars f/r and my rear is always on the softest setting. im in the process of trying to get the spring rate right, but i dont think i will wind up going up on the bar.
HIN this weekend.
Still was not 100%, missing alot of bits to the aero package still and the blots from the bumper to the fender, lol, that panel gap :SMH: Still cant believe i forgot to bolt it on.

Man you are flying! Love the pops too, you running negative timing at low loads high rpm? Also, why is your 5th gear so deep, track specific? Seemed like you needed something closer ratio. Either way, awesome clip (and awesome camera position, sweet footwork!)

What are the dimensions of the robispec bar? 27mm bar? Also, what are your spring rates if you don't mind me asking? The rear aero you have in that vid is a bit confusing, lol.
EDIT: just saw your at 700 lbs at all 4 corners. How much does the car weigh? That seems very balanced and pretty moderately sprung for a full race aero car. I'm starting to jump on the wagon of lower spring rates and cranked up low speed damping to maintain response. Compliance is key and is difficult to measure and get right. I'd love to hear an in depth review on those penske's. They're in the realm of top ohlins, MCS, and Nitron's and i'm really curious as to how they would compare. FYI i have KW's and the more i track them, the more i'm becoming dissatisfied with them. I even have the robispec versions which supposedly have better damping but the high speed damping built into the dampers is crap. I'm begining to think that at this price range, the Ohlins R&T or Fortune Auto dreadnaughts are a MUCH better coilover....
Oh, and from what i hear, the JRZ and Moton's today can't compare to the MCS. I find it interesting that the guys who started MCS, also started JRZ and Moton. I wonder why they keep jumping ship....

We were still running stock Evo 8 gearing in the video so 5th gear is less than ideal. We got a TRE with the ultimate ratio trans and an HKS 4:11, so it should be much better now.
The rear bar is a 26mm, which we run 1 click down from full stiff as Roostinds mentioned. IIRC, Robi said the softest setting is equal to a progress 25 on full stiff. At Superlap Battle and this video we were about 2900 to 2950lbs race weight.
You are right about the KW V3's at high speed, and not being very responsive. But it is a mass produced shock that is made to go 100k miles and be driven on the street as well as the track. They aren't that bad though. We still went Sub 1:50 on them, and were able to match the min speeds and even exceed some of the min speeds in some sections set by Pro Awesome on their record lap. SLB was the first time I ever drove on TD's however, it's crazy how much grip they have!
The Anze Penskes are on a whole other level. The car feels like a big go kart and is very agile, changes directions on a dime, but still soaks up berms without upsetting the balance of the car. The KW V3's feel sloppy in comparison. Steering feel is much more crisp and precise, and turn in is even better than before. We still have to make some tweaks to increase front grip some more, as you can see in the video. The tires were a bit aged and far from fresh, but we still went over a second faster than the V3's with some traffic. We need to do some more testing with fresh tires and make some more tweaks from there.

Thanks so much for sharing your experience!! I am adding a lip and a splitter up front and am currently debating if adding the pw JDM rear gurney would provide enough downforce to even it out or if i have to get a GT wing. The splitter will probably only be 2 inches long. I want to build my car to the Pirreli world challenge spec which means my splitter can only protrude a max of 2 inches from the front bumper when viewed from above, and any rear spoiler i have cannot be wider than 1500 mm.
Voltex gets my vote. But with a 2" splitter, you might be able to get away with the gurney, especially if your sticking to a budget. But, it's hard to say if the aero balance will be good without testing it. Keep in mind you won't have any adjust-ability with the with the Password JDM piece. Also, I would imagine that the gurney would add a lot more drag than compared to the Voltex. From what others have told me, there is no point in making a gurney bigger than than a 1/2". The Password JDM peice looks to be a mix of a gurney and a wing extension of some sort.
the gurney flap i made for my car is 1.5% of the chord length. i have no wind tunnel to test it, but we'll see how it handles Riverside, next time i'm at Buttonwillow
not GT wing for me until i get my splitter finished. er... started. LOL
