Front - corona length LCAs, ae86 PS arms, coilovers with 8kg springs and shocks to suit (SW20 MR2 rear shocks and techno toy tuning spacer would be good), rebuild brakes if keeping T18 struts otherwise upgrade to something a little bigger nothing over the top (its only a sub 1ton car)

 

and there is not really much you can do about the steering box just get a ke70 xmember and cut the t series mounts off the old one and weld them onto the ke one (what I will be doing with mine) then use a ke70 steering shaft with uni joint.

 

For the rear get 6kg springs + short stroke shocks, get swaybar mounts and weld them on if yours doesn't have a rear swaybar like mine, go on ebay US and get a brace kit of there for an ae86 (about $150AUD delivered) includes front strut brace, rear strut brace and a C pillar brace.

 

AS well as some good wheels and wider tyres, then build a very nice 3tg hybrid.

8kg is a bit over the top....

 

i have 6kg in the front of the ke70 at the moment, if i had better shocks (i only have excel g's...cheap!) i would be putting in softer ones, but the excel-g shocks are only just passable on the 6kg's. (i also cannot be stuffed as i just put up with it for the time being)

 

forget those 8kg/6kg springs, spend all your cash on a set of bilstein or koni shocks (or simliar GOOD shocks), and go for something like 5kg and 4kg, or even 4kg and 3kg.

 

(i am unsure as to why we always put slightly softer springs in the rear...given that it should be pretty close to 50/50 weight distribution, let the rear squat a bit for more grip perhaps?)

 

you just don't need 8kg/6kg in a sub 1000kg car. your teeth will break.

 

i know this because i had 8kg/6kg a few yrs back, i got talked into it on the internet as being "the thing to do". little did i know that those spring rates were perfect for driving on a billiard table. but that is about it.

 

in the real world you need soft springs, and good shocks.

couple reasons for softer in the rear, engine in the front, so theres going to be more weight (but then again theres a diff in the back). Also its more so to do with drifiting, you want more body roll in the rear so the rear end goes out easier which is why you'd have softer spring rates in the rear.

 

Well thats just my understanding of it.

It could be 8 in the front on mine not to sure at work at the moment but i can put all my wait and i can barley move the front end up and down and i way 90kg

what springs are they? if they are king springs then they won't be 8kg or 6kg unless they are coilover springs, the 8kg springs in mine you cannot move the car at all when you sit on it or try to bounce it, also off topic those quad lights need the guards to be cut up and shortened and remade pretty much to fit those quad lights on T18.

8kg referes to 8kg/mm

 

so for every milimeter of movement in the spring, it requires 8kg of weight on top of it.

 

so if you weigh 90kg, you will get around 11mm of deflection in the spring if you sit on it. which is not alot.

 

you will get more if you bounce up and down though.

 

(edit, assuming the spring is linear)
