After finding out the prices for my very limited choices last June I really got into looking around for solutions.STIMPV1 said:Sounds like you've done your homework on rims.
I have seen someone driving at the road track with the Rotas and they worked fine for him. I spoke to the person at subydude.com who also indicated the Rota SDRs in 17x7.5 will fit the STi. I have no idea what tire size these people are using though. The Prodrive link below indicates a 48mm offset for their 17x7.5 wheels which they claim fit the STi.Do you know for certain that the 48mm offset will not cause the tires to rub? I wouldn't think so but want to confirm before I drop $$$.
I haven't really looked at them. They do look attractive and the price isn't too bad though the SSR's should be a bit cheaper. The 17x8's use a ET43 offset -- is that going to work well? Don't know.
The PSI3 SECS unit is made by PSI^3 Automotice Technology in England, and resold by a number of places in the States, including Quantum Racing. It plugs into the ODB-II port underneath the steering wheel, and then displays all kinds of info from the ECU. It's a breeze to install since there is just that one plug which includes power. Shows things like road speed, RPM, intake air temperature, coolant temperature, throttle percentage, boost, and so on. It will keep track of the peak value for some items, which is handy for speed (everyone always wants to know how fast you went, and this keeps you from having to look at the speedo or do all the calculations in your head (OK, so if I was at about 5000 rpm in 6th, that means I was doing...? mph).What is the PSI3 unit? I know the speedoff is off by exactly what you say. I'm surprised to see that the ECU knows what's going on. Thanks for any info.
