Lord
the wheels are 10"x18" ET40 front and 11"x18" ET35 (with the spacer adapters) and I can tell you that my car can be full lowered with out rubbing problems but due a soft spring they are touching the top of the fenders but only the top and only at the front.
For some reason I was under the impression that your ET was over 50...

and I know that the 660 slick diameter is not the ideal (stock diameter is 624) but on a second hand slicks is what i can get
I tryed to fit the biggers rims I can with the standar rolled fenders (homologation limits)
I was thinking that the wheel track is bigger now than the standar from factory.... i will see
It sucks that the FIA losers REQUIRE standard rolled fenders ,this is a huge limitation. You are extremely lucky that you wre able to get homologation (probably with organization representing FIA in Spain) ,in most EU countries this is not even remotely ($$$ = bribe) possible especially with bolt on cage.

NO at the moment standar subframe bushings
can you tell me the avantages???
Huge advantages ,this is a GT car with GT style inserts for the the sub-frames - in other words LOTS of flex from the factory. Now add 25 years of use to that...

with a harder spring rates ,it will be lowered more than now but taking care of the roll center point and the speed bumps height here in Spain , here in my town the town hall tourned mad puting a lot of speed bumps on all streets !!!!
I hear you ,with my car I have some real hard time getting out of my driveway (no bumps at all ,just a driveway going into the street). Roll center is another big concerned when car is lowered too much...

yes it is thruth , our wheel base is not the ideal and like you say we need to get as big wheel tack as possible.
But on my last track day test my supra was as fast on low speed corner as low wheel base race cars (TRACK EVO and CLIO CUP CARS) and was fasted on a hig speed corners so i am happy , like a told you , i want to eliminate a little bit the body roll and a 2.5º negatie camber plus my powerfull engine and plus the dog box 6 speeds wowwww!!! IT can be a fast car! jejeje
I tried to eliminate the standard track differences , so now a line i the middle of the tires is the same front and back, I had no information about what is the best wheel track and I was suppousing that the oversteer problems came by that track difference... I have room to play anyway.
now I am talking with a companny who can make a custom made coilovers with a separate rebound and compression adjustment, the last thing is the spring rate choice.
but reading your comments about yours dampers.... if you say those are mutch better than the RAs I will consider that option.
Well if you have money to spend you can always talk to Ohlins ,at least they are not too far from you

I want to show you some ideas I have to get the car lowered with out loose the roll center point or almost get the supra very low maintaining the suspension arm angels as better as possibe.
uhmm I`ve seen those custom lower arms before in other forum.... I just started with my proyect after see that thread and also I took some ideas like the woodward stering column but I prefer to move the camber at the top because it dosnt change the track and also it will no need to adjust the toe a lot.
I like to have the possibility of adjust everything at the track.
wait till I send you the FIA book where are all the different suspension arms toyota made.
with 2.5º-3º of neative camber will be sufficient for me and with the double wishbonne also ....yes??? it is what Dunlop and Toyo recomend for theirs race tyres
I would not consider too much Toyo or Dunlop recommendations ,unless they make them as some common baseline. McPherson and Double Wishbone car would have totally different static camber. Once you get a way to adjust it you will find what is ideal for you all that you need is a temp sensor and practice runs. For me I found that these
Alignment specs work best for my car and my tires (Dunlop Direzza Star Spec) ,for example if I add more camber in the front the car steers better but my breaking points go up with one mark ,if I add more camber in the rear my exit corner acceleration traction is gone... It is all practice ,practice...

yes my doors are a carbon fibre door set from Japan they only weight 2,5 kg each but I still have the electric windows lifters and the stock heavy mirrors. (seeking a companny who can make a mirros plates in carbon to fit a F1 style carbon mirrors)
if in the furture I use the car only at the tracks , my plan is to get a set of plexi glass fron Japan (rear, doors and sides) no windows lifters , bigger custom made carbon fenders DTM style front and rear (I have a friend who can make it here sheap) set the engine at lower possition than now , front lip and cannards, rear carbon hatch, no front beams and the electric motors.... and maybe it will be close to 1250 kg. ehh?
I guess that the FIA losers REQUIRE you to have windows? The most FRENCH (stupid) requirement in the motorsports world... 1250 will be very very difficult ,but you can get close with all these mods.
