clap Greatest thing is actually it really hasnt cost half that!!! everything has been brough on group buys, sourced from the states or even used.... for example.. the APs cost 3.5k new i got them for just over 2k with 500 miles use!! just bed in for me ;-)

every single item is purchased at a discount usually ;-)
Fair play to you that seems quite a car for under 40k to me smile
See you do this sprint thing at corbrough which is up the road from me near enough what do you have to do to get involved? Would love to take the mini along one of the day's and have a look at this in the flesh

They are great.
Robust
I got them to dyno my stock suspension to help select the right valving and spring rates.
I ended up with 320 lbs all round. I had lock rings & pillow mounts allround with remote adjusters on the rears.
That let me get a 35mm drop with a very compliant ride.
It was set ~1/3 from minimum on rebound and compression for road use.
Stiffend it right up for track days.
Three tips
1) make sure you torque up the suspension when it is underload
2) approximate the height & Geo you want then let it settle for a couple of weeks.
3) Once it's settled make sure you get it corner weight and the geo set properly

ok suspension is on its way.....


cars booked into chris @ center gravity for a complete 2 days session!! every single part of the setup will be finessed. from bump and rebound to camber/ castor....... the car should be pretty AWESOME.

also went for some reinforced rear shock mounts from us company rogue engineering... Completely rebuildable, cnc brackets, will protect the mount points from harder suspension, But the best bit is the reversed top section which allows me to complete remove and install the rear dampers frum under the car... after install no more having to remove the whole boot carpet and trims :-)

Brilliant car. Would love to see this in the flesh. Looks like you are doing everything the 'right' way with regards to modding as well.

i choose the roadster because it was the car i wanted...... designed as a roadster from the off, hugely stiff chassis, stiffer thn alot of coupe's :-) i have All the fun of a coupe with the best bits of a roadster, roofless on the track is imo motoring nervana, everything the coupe offers but with the the added open air theatre.... this car is MY expression of building perfection :-)

R.e the parts ive used the best available...... vmax is need this summer to test her out against the supercars

As I commented earlier on this thread, I think this car is great.

I dont have the time, dedication, or if I'm honest, the inclination to hone a car to such a degree. But I am in awe of such single mindedness.

Im lazy and bought my cars straight out of the box, but this is the only "modified car" on PH that interests me in the slightest...

Honestly i agree with you...i wish i could afford the 458s/ mp4 12cs and not need to do anything straight out the box!! That would be awesome, unfortunatly those type of car Are alittle way off for me, but i will get their one day for sure..... i already have a savings account opened and funds saving for my dream car.... the mp4 12c... which is WILL own!

until that time i figure if i can get the car to 1200kg.... with this power and kit the car will be a serious performer, honestly right now i cant see a sub 80k car that will outperform this car ive build, if i did i dont think i would have spent the time to do this, but then again its taken 3 years to get the car to where it is now.....

gallardoguy... thanks for the comments, its always nice when people GET where your coming from on a build like this.
